SSH Control

"SSH supports two different protocol versions. The original version, SSHv1, was subject to a number of security issues. Please use SSHv2 instead to avoid these."

How will I verify this?

Whip up a one-liner!

grep "^Protocol" /etc/ssh/sshd_config | sed 's/Protocol //'

Apache Server Information Leakage

• Description

This Directive Controls wheather Server response field is sent back to clients includes a description of Generic OS Type of the Server.

This allows attackers to identify web servers details greatly and increases the efficiency of any attack,as security vulnerabilities are dependent upon specific software versions.

• How to Test

In order to test for ServerToken configuration, one should check the Apache configuration file.

• Misconfiguration

ServerTokens Full

• Remediation

Configure the ServerTokens directive in the Apache configuration to value of Prod or ProductOnly. This tells Apache to only return "Apache" in the Server header, returned on every page request.

ServerTokens ProdorServerTokens ProductOnly

More grep and sed!

grep "^ServerTokens" /etc/httpd/conf/httpd.conf | sed 's/ServerTokens //'

Compliance

Two-thirds of organizations did not adequately test the security of all in-scope systems

Key Trends

• While individual rule compliance is up, testing of security systems is down

• Sustainability is low. Fewer than a third of companies were found to be still fully compliant less than a year after successful validation.

Shell Scripts

grep "^Protocol" /etc/ssh/sshd_config | sed 's/Protocol //'grep "^ServerTokens" /etc/httpd/conf/httpd.conf | sed 's/ServerTokens //'

Infrastructure Code

package 'httpd' doaction :install

end

service 'httpd' doaction [ :start, :enable ]

end
