Poor content security can also increase the likelihood of systems falling victim to a virus or Trojan attack. Even if the network's external defenses are sound, a lack of content security at the desktop could allow contaminated material downloaded onto mobile devices or laptops to spread onto the corporate network. That's why it is also necessary to develop and enforce policies for the use of mobile equipment on internal networks.

To guard against threats, it is important that regularly updated content filtering, anti-virus and anti-spam solutions are implemented at the desktop level and at the network gateway level. Ceptera has experience providing independent advice on the selection, design and implementation of content security solutions. Ceptera also offers forensic investigation and testing services to determine whether system filtering and monitoring processes are stringent enough to prevent sensitive material passing out of the organization.
