Web Security Overview
Warning
HTTPS

Web sites need to use encryption to help their visitors know they're in the right place, as well as provide confidentiality and content integrity. Sites that don't support HTTPS may expose sensitive data and have their pages modified and subverted.
There are issues with this site's HTTPS configuration.

For all sites VERY IMPORTANT medium EFFORT
Supported and well configured
HTTPS Redirection

To deploy HTTPS properly, web sites must redirect all unsafe (plaintext) traffic to the encrypted variant. This approach ensures that no sensitive data is exposed and that further security technologies can be activated.

For all sites VERY IMPORTANT low EFFORT
Warning
HTTP Strict Transport Security

HTTP Strict Transport Security (HSTS) is an HTTPS extension that instructs browsers to remember sites that use encryption and enforce strict security requirements. Without HSTS, active network attacks are easy to carry out.
There are issues with this site's HSTS configuration.

For important sites VERY IMPORTANT medium EFFORT
Not supported
HSTS Preloaded

HSTS Preloading is informing browsers in advance about a site's use of HSTS, which means that strict security can be enforced even on the first visit. This approach provides best HTTPS security available today.

For important sites VERY IMPORTANT medium EFFORT
Supported and well configured
Content Security Policy

Content Security Policy (CSP) is an additional security layer that enables web sites to control browser behavior, creating a safety net that can counter attacks such as cross-site scripting.

For important sites IMPORTANT high EFFORT
Email Security Overview
Supported and well configured
STARTTLS

All hosts that receive email need encryption to ensure confidentiality of email messages. Email servers thus need to support STARTTLS, as well as provide decent TLS configuration and correct certificates.

For all sites VERY IMPORTANT low EFFORT
Supported and well configured
SPF

Sender Policy Framework (SPF) enables organizations to designate servers that are allowed to send email messages on their behalf. With SPF in place, spam is easier to identify.

For important sites IMPORTANT low EFFORT
Supported and well configured
DMARC

Domain-based Message Authentication, Reporting, and Conformance (DMARC) is a mechanism that allows organizations to specify how unauthenticated email (identified using SPF and DKIM) should be handled.

For important sites IMPORTANT low EFFORT

Domain Registration

Your security begins with the security of your domain name. If someone takes control of your domain name then they can update the name server configuration to send users elsewhere, or they can transfer the domain name to another party. For best results, fully lock your domain names at registry and registrar levels.

Test passed
Everything seems to be well configured. Well done.

Registration Data Access Protocol (RDAP)

The RDAP protocol enables users to access current registration data and was created as an eventual replacement for the WHOIS protocol. RDAP has several advantages over the WHOIS protocol, including support for internationalization, secure access to data, and the ability to provide differentiated access to registration data.

WHOIS

WHOIS is a TCP-based transaction-oriented query/response protocol that is widely used to provide information services to Internet users. While originally used to provide "white pages" services and information about registered domain names, current deployments cover a much broader range of information services.

DNS Zone

The global DNS infrastructure is organized as a series of hierarchical DNS zones. The root zone hosts a number of global and country TLDs, which in turn host further zones that are delegated to their customers. Each organization that controls a zone can delegate parts of its namespace to other zones. In this test we perform detailed inspection of a DNS zone, but only if the host being tested matches the zone.

Test passed
Everything seems to be well configured. Well done.

Nameserver Names

Nameservers can be referred to by name and by address. In this section we show the names, which can appear in the NS records, the referrals from the parent zone, and the SOA record. In some situations, servers from the parent zone respond authoritatively, in which case we will include them in the list as well.

Nameserver Addresses

This section shows the configuration of all discovered nameservers by their IP address. To find all applicable nameservers, we inspect the parent zone nameservers for names and glue and then the tested zone nameservers for NS records. We then resolve all discovered names to IP addresses. Finally, we test each address individually.

Start of Authority (SOA) Record

Start of Authority (SOA) records contain administrative information pertaining to one DNS zone, especially the configuration that's used for zone transfers between the primary nameserver and the secondaries. Only one SOA record should exist, with all nameservers providing the same information.

The domain name of the primary nameserver for the zone. Also known as MNAME.Primary nameserver ns1.cisco.com.
Email address of the persons responsible for this zone. Also known as RNAME.Admin email postmaster.cisco.com.

The length of time after which secondary nameservers should stop responding to queries for a zone, assuming no updates were obtained from the primary.Expire interval 864,000 seconds (about 10 days)
TTL for purposes of negative response caching. Negative cache TTL 1,800 seconds (about 30 minutes)
Time To Live (TTL) indicates for how long a record remains valid. SOA record TTL 1,800 seconds (about 30 minutes)

DNS Records

Correctly functioning name servers are necessary to hold and distribute information that's necessary for your domain name to operate correctly. Examples include converting names to IP addresses, determining where email should go, and so on. More recently, the DNS is being used to communicate email and other security policies.

Test passed

DNSSEC

DNSSEC is an extension of the DNS protocol that provides cryptographic assurance of the authenticity and integrity of responses; it's intended as a defense against network attackers who are able to manipulate DNS to redirect their victims to servers of their choice. DNSSEC is controversial, with the industry split largely between those who think it's essential and those who believe that it's problematic and unnecessary.

Useful DNSSEC Tools

Certification Authority Authorization

CAA (RFC 8659) is a new standard that allows domain name owners to restrict which CAs are allowed to issue certificates for their domains. This can help to reduce the chance of misissuance, either accidentally or maliciously. In September 2017, CAA became mandatory for CAs to implement.

Analysis

Powerup!
Issuance of S/MIME certificates not restricted
This policy doesn't restrict the issuance of S/MIME certificates. Consider using the `issuemail` directive to restrict which CAs, if any, can issue.
Powerup!
Issuance of BIMI not restricted
This policy doesn't restrict issuance of BIMI certificates. Consider using the `issuevmc` directive to restrict which CAs, if any, can issue.
Good
CAA policy restricts issuance
Great. This domain name uses CAA to restrict which CAs are allowed to issue certificates for it.
Good
Policy uses reporting
Good. This policy uses reporting, which means that your contact information is available should someone need to contact you about a CAA violation. Do note that you're not guaranteed to be notified, given that CAs generally don't support notifications yet.

Email (SMTP)

An internet hostname can be served by zero or more mail servers, as specified by MX (mail exchange) DNS resource records. Each server can further resolve to multiple IP addresses, for example to handle IPv4 and IPv6 clients. Thus, in practice, hosts that wish to receive email reliably are supported by many endpoint.

Notice
Some SMTP server assessments have been retrieved from cache
Some SMTP server assessment results have been retrieved from our cache. Because many hosts point to the same SMTP servers, we use a short-term cache to avoid testing the same SMTP servers over and over again.

Latest cache timestamp: 18 Nov 2024 10:38 UTC

Earliest cache timestamp: 18 Nov 2024 10:38 UTC

Notice
Some SMTP server assessments contain partial information
Comprehensive TLS assessments require many connections, which is exactly what many SMTP servers don't like. We implement a two-tier assessment approach. To give you some results as fast as possible, we perform shallow assessments that use only one connection per SMTP server. We then have a background process that performs complete assessments slowly, trying to accommodate each server individually. The results presented here contain partial information. If you come back later we may be able to provide complete assessment resuls.

Email TLS (SMTP)

Transport Layer Security (TLS) is the most widely used encryption protocol on the Internet. In combination with valid certificates, servers can establish trusted communication channels even with users who have never visited them before. Network attackers can't uncover what is being communicated, even when they can see all the traffic.

Notice
Relaxed TLS assessment criteria applied to SMTP on port 25
We apply relaxed assessment criteria when evaluating TLS configuration of SMTP servers on port 25. This is because most delivery agents fall back to delivering via plaintext on failure to negotiate encryption. Some configuration elements that can be abused to attack other ports and protocols (e.g., SSLv2 and export cipher suites) are penalized in the same way as for other protocols. We will review this policy in the future.

Email Certificates (SMTP)

A certificate is a digital document that contains a public key, some information about the entity associated with it, and a digital signature from the certificate issuer. It’s a mechanism that enables us to exchange, store, and use public keys. Being able to reliably verify the identity of a remote server is crucial in order to achieve secure encrypted communication.

Email DANE (SMTP)

DNS-based Authentication of Named Entities (DANE) is a bridge between DNSSEC and TLS. In one possible scenario, DANE can be used for public key pinning, building on an existing publicly-trusted certificate. In another approach, it can be used to completely bypass the CA ecosystem and establish trust using DNSSEC alone.

MTA Strict Transport Security

SMTP Mail Transfer Agent Strict Transport Security (MTA-STS) is a mechanism enabling mail service providers to declare their ability to receive Transport Layer Security (TLS) secure SMTP connections, and to specify whether sending SMTP servers should refuse to deliver to MX hosts that do not offer TLS with a trusted server certificate.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

SMTP TLS Reporting

SMTP TLS Reporting (RFC 8460), or TLS-RPT for short, describes a reporting mechanism and format by which systems sending email can share statistics and specific information about potential failures with recipient domains. Recipient domains can then use this information to both detect potential attacks and diagnose unintentional misconfigurations. TLS-RPT can be used with DANE or MTA-STS.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

WWW TLS

Transport Layer Security (TLS) is the most widely used encryption protocol on the Internet. In combination with valid certificates, servers can establish trusted communication channels even with users who have never visited them before. Network attackers can't uncover what is being communicated, even when they can see all the traffic.

Analysis

Powerup!
TLS 1.3 not supported
TLS 1.3 is the latest revision of the TLS protocol and a significant improvement over earlier versions. Developed over a period of several years and extensively analyzed prior to the release, TLS 1.3 removed insecure features, and improved both security and performance. This version of TLS should be the main protocol used with modern clients.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which can provide strong security when configured correctly. This version of the TLS protocol is necessary to provide good security with a wide range of clients that don't yet support TLS 1.3.
Good
Deprecated protocols not supported
Excellent. This server doesn't support any of the deprecated protocol (TLS 1.1 and earlier).
Warning
Weak key exchange
This server uses key exchange parameters that are weak. When using the ephemeral Diffie-Hellman key exchange (DHE), parameters below 2048 bits are considered weak. For sufficient security, use 2048-bit parameters. It is generally not advisable to use stronger DHE key exchange because there is a measurable performance penalty and there is no meaningful increase in security. A well-configured TLS server should generally prefer the faster ECDHE key exchange anyway. When it comes to ECDHE, aim for at least 256 bits; anything below 200 bits is weak. For best results, use secp256r1 and secp384r1, which are required in practice, and x25519 as an emerging standard.

Weak parameters: DH 1024

Good
Server prefers forward secrecy and authenticated encryption suites
Excellent. Not only does this server enforce its server preference, but it also has at the top of the list suites that support both forward secrecy and authenticated encryption. This is the best TLS 1.2 can offer.
Good
Server enforces cipher suite preferences
Excellent. This server enforces server cipher suite preference, which means that it is able to select the best suite from the options submitted by clients. Combined with a well-designed list of supported cipher suites, this setting enables negotiation of best security.
Good

Developed over a period of several years and extensively analyzed prior to the release, TLS 1.3 removed insecure features, and improved both security and performance. This version of TLS should be the main protocol used with modern clients.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which can provide strong security when configured correctly. This version of the TLS protocol is necessary to provide good security with a wide range of clients that don't yet support TLS 1.3.
Good
Deprecated protocols not supported
Excellent. This server doesn't support any of the deprecated protocol (TLS 1.1 and earlier).
Warning
Weak key exchange
This server uses key exchange parameters that are weak. When using the ephemeral Diffie-Hellman key exchange (DHE), parameters below 2048 bits are considered weak. For sufficient security, use 2048-bit parameters. It is generally not advisable to use stronger DHE key exchange because there is a measurable performance penalty and there is no meaningful increase in security. A well-configured TLS server should generally prefer the faster ECDHE key exchange anyway. When it comes to ECDHE, aim for at least 256 bits; anything below 200 bits is weak. For best results, use secp256r1 and secp384r1, which are required in practice, and x25519 as an emerging standard.

Weak parameters: DH 1024

Good
Server prefers forward secrecy and authenticated encryption suites
Excellent. Not only does this server enforce its server preference, but it also has at the top of the list suites that support both forward secrecy and authenticated encryption. This is the best TLS 1.2 can offer.
Good
Server enforces cipher suite preferences
Excellent. This server enforces server cipher suite preference, which means that it is able to select the best suite from the options submitted by clients. Combined with a well-designed list of supported cipher suites, this setting enables negotiation of best security.

WWW Certificates

A certificate is a digital document that contains a public key, some information about the entity associated with it, and a digital signature from the certificate issuer. It’s a mechanism that enables us to exchange, store, and use public keys. Being able to reliably verify the identity of a remote server is crucial in order to achieve secure encrypted communication.

Certificate Trust

Determining whether a certificate is considered valid is a complicated process that depends on the exact configuration of the validating party. For trust to be established, the certificate must form a chain that ends with a trusted root. In this section we evaluate the server's certificate against major root stores.

DANE (443)

DNS-based Authentication of Named Entities (DANE) is a bridge between DNSSEC and TLS. In one possible scenario, DANE can be used for public key pinning, building on an existing publicly-trusted certificate. In another approach, it can be used to completely bypass the CA ecosystem and establish trust using DNSSEC alone.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

Cookies

Cookies are small chunks of text that are sent between your browser and a website. They are often essential to the operation of the site and sometimes contain sensitive information. Session cookies sent from secure sites must be explicitly marked as secure to prevent being obtained by active network attackers.

Test passed
Everything seems to be well configured. Well done.

HTTP Cookie: c_bi

Cookie value. As far as the cookie RFC is concerned, the value
is an opaque string which only the application should interpret.
Value
5271b227c1594565901f44f431a3aa32
Cookie domain. When domain is implied (not explicitly set in a cookie),
most browsers (but not IE) treat the cookie as host-only, meaning that
no other server can overwrite it.
Domain
www.cisco.com
Cookie path. This field can't be used as security measure,
but it could be of use to avoid cookie name collision
in non-adversarial contexts.
Path
/
The HttpOnly flag prevents the cookie from being accessed
from JavaScript, thus making them more difficult
to obtain after a successful XSS attack.
HttpOnly
The Secure flag signals to browsers that the cookie
should be transmitted only over an encrypted channel.
Secure
Normally, when a browser makes a request to a web site,
it sends all associated cookies. This is not always
desirable, because it might allow third-party sites
to perform site actions under the identity of the user.
This attack is known as Cross-Site Request Forgery.
With SameSite cookies (still in development, but already
supported in some browsers), you can choose to be more
strict. The possible values are 'lax' and 'strict'.

Good. This cookie is marked secure, which means that it won't ever be transmitted over plaintext. As such, it's not vulnerable to the Sidejacking attack.

HTTP Cookie: CP_GUTC

Cookie value. As far as the cookie RFC is concerned, the value
is an opaque string which only the application should interpret.
Value
23.218.223.5.172221732153506838
Cookie domain. When domain is implied (not explicitly set in a cookie),
most browsers (but not IE) treat the cookie as host-only, meaning that
no other server can overwrite it.
Domain
cisco.com
Cookie path. This field can't be used as security measure,
but it could be of use to avoid cookie name collision
in non-adversarial contexts.
Path

Cookies are designed to always expire. Session cookies
are truly ephemeral and remain cached until the browser
is closed. The Expires and Max-Age cookie attributes can
be used to specify that a cookie should stay alive for
longer.
Expires
Fri Oct 26 01:45:06 UTC 2029 (4 years 11 months)
The HttpOnly flag prevents the cookie from being accessed
from JavaScript, thus making them more difficult
to obtain after a successful XSS attack.
HttpOnly
The Secure flag signals to browsers that the cookie
should be transmitted only over an encrypted channel.
Secure
Normally, when a browser makes a request to a web site,
it sends all associated cookies. This is not always
desirable, because it might allow third-party sites
to perform site actions under the identity of the user.
This attack is known as Cross-Site Request Forgery.
With SameSite cookies (still in development, but already
supported in some browsers), you can choose to be more
strict. The possible values are 'lax' and 'strict'.

HTML Content

On virtually all web sites, HTML markup, images, style sheets, JavaScript, and other page resources arrive not only over multiple connections but possibly from multiple servers and sites spread across the entire Internet. For a page to be properly encrypted, it’s necessary that all the content is retrieved over HTTPS. In practice, that’s very often not the case, leading to mixed content security problems.

Test passed
Everything seems to be well configured. Well done.

Encryption of Embedded Resources

In this section we look at the transport security of all embedded resources. Mixed active content occurs when there are unprotected scripts or styles embedded in a page. This is typically not allowed by modern browsers. Mixed passive content (images, videos and such) are typically allowed, but shouldn't be present.

  9 out of 9 are secure  View all
3 CSS file(s)
  3 out of 3 are secure  View all
7 media file(s)
  7 out of 7 are secure  View all

Encryption of Outbound Links

Ideally, an encrypted page should only have links that lead to other encrypted pages. If plaintext links are used, passive network attackers can see where people go after they visit your web site. It's also possible that some sensitive information is leaked in the Referer header.

  2 out of 2 are encrypted  View all

HTTP Strict Transport Security

HTTP Strict Transport Security (HSTS) vastly improves security of the network encryption layer. With HSTS enabled, browsers no longer allow clicking through certificate warnings errors, which are typically trivial to exploit. Additionally, they will no longer submit insecure (plaintext) requests to the site in question, even if asked.

Test passed, but there are warnings
Some aspect of your site's configuration require your attention.

HSTS Policy  Main host

URL from which this policy was obtained.Location https://www.cisco.com/
Specifies policy duration. Once activated, HSTS stays in force
until this time lapses. Browsers update policy cache duration
every time they receive a new HSTS header from a site.
max‑age
31,536,000 seconds (about 1 year)
When present, this directive forces HSTS activation
on allsubdomains. For best security, HSTS should be
deployed on the bare domain name (e.g., example.com)
and all its subdomains.
includeSubDomains
Presence of this directive indicates that a web site wishes to
permanently use HSTS and that its policy information should be
preloaded (embedded in browsers).
preload

Analysis

Good
Policy is valid
OK. Your HSTS policy uses correct syntax.
Good
Long policy age
Your HSTS policy has a long max-age value, which offers better protection.
Powerup!
No subdomains
This HSTS policy doesn't cover subdomains. Without full coverage, HSTS can't protect from certain cookie attacks that typically allow active network attackers to inject cookies into an application. Additionally, subdomain coverage is one of the requirements to allow preloading.
Notice
Preload directive has no effect here
This policy doesn't enable preloading, but that's all right. The preload directive doesn't have any effect unless it's used on an apex hostname.
Good
Redirection from HTTP to HTTPS to the same host
Good. The redirection from HTTP to HTTPS is to the same host. This approach ensures that HSTS is activated on the hostname when it's accessed via plaintext.
Powerup!
No parent protection
This host could benefit from further protection if the apex hostname would be configured with a HSTS policy that uses 'includeSubDomains'. Enabling HSTS on an entire domain name is the only approach that provides robust security.

Analysis

Warning
Policy set on plaintext port
HSTS policies must not be transmitted over insecure channels.

HTTP Public Key Pinning

HTTP Public Key Pinning (HPKP) enables site operators to restrict which certificates are considered valid for their domain names. With a valid HPKP configuration, sites can defeat man in the middle (MITM) attacks using fraudulent or misissued certificates. HPKP is an advanced feature, suitable for use by only high-profile web sites.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

Content Security Policy

Content Security Policy (CSP) is a security mechanism that allows web sites control how browsers process their pages. In essence, sites can restrict what types of resources are loaded and from where. CSP policies can be used to defend against cross-site scripting, prevent mixed content issues, as well as report violations for investigation.

Subresource Integrity

Subresource Integrity (SRI) is a new standard that enables browsers to verify the integrity of embedded page resources (e.g., scripts and stylesheets) when they are loaded from third-party web sites. With SRI deployed, remote resources can be used safely, without fear of them being modified by malicious parties.

The homepage of this site doesn't contain any remote resources so SRI is not needed.

Expect CT

Expect-CT is a deprecated response HTTP header designed to enable web sites to monitor problems related to their Certificate Transparency (CT) compliance. Should any CT issues arise, browsers that supported this header will submit reports to the specified reporting endpoint. Chrome was the browser that introduced support for this response header, but later deprecated it and removed it in version 107.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

Analysis

Powerup!
Deploy Expect-CT to enable reporting
An Expect-CT policy enables web sites to monitor for any problems related to their Expect-CT compliance, detecting potentially serious issues quickly. When issues arise, compliant browsers will submit reports to the specified reporting endpoints. Before CT became required for all public certificates the Expect-CT was also used to require CT, but that use case no longer applies.

Frame Options

The X-Frame-Options header controls page framing, which occurs when a page is incorporated into some other page, possibly on a different site. If framing is allowed, attackers can employ clever tricks to make victims perform arbitrary actions on your site; they do this by showing their web site while forwarding the victim's clicks to yours.

Test passed
Everything seems to be well configured. Well done.

Framing allowed from the same origin only
OK. Your site allows page framing only from itself. This should generally be safe, except maybe on sites that host user content.

XSS Protection

Some browsers ship with so-called XSS Auditors, built-in defenses against XSS. Although these defenses work against simple reflective XSS attacks, they can be abused by skillful attackers to add weaknesses to otherwise secure web sites. These dangers are present in both filtering and blocking modes. At this time, the Safari browser ships with its XSS defenses enabled by default. For this reason, the best approach is to explicitly disable this functionality.

Feature not applicable, not implemented, or disabled
Your server doesn't support this feature.

Analysis

Powerup!
Explicitly disable browser XSS protection
For best security, every web site should explicitly disable browser-based XSS protection. This is because this type of functionality can be used to introduce vulnerabilities into otherwise error-free web sites.

Content Type Options

Some browsers use a technique called content sniffing to override response MIME types provided by HTTP servers and interpret responses as something else (usually HTML). This behavior, which could potentially lead to security issues, should be disabled by attaching an X-Content-Type-Options header to all responses.

Test passed
Everything seems to be well configured. Well done.
