Internet Security: Beyond the Firewall
In today’s complex and ever-changing world of internet security, organizations around the world are trying to find the most effective strategy to secure their digital resources. For the past several years, traditional security products like firewalls and anti-virus software have been used heavily as a total solution. However, these products are becoming antiquated at an alarming rate as todays viruses and security threats are becoming more sophisticated and numerous. Experts discover thousands of new vulnerabilities daily, and many organizations unfortunately fail to realize that traditional means of security, such as firewalls, only address a portion of the potential risks and may contribute to a false sense of security. A more complete approach is one that layers existing traditional technologies with other tools that attempt to fill in the security holes. ... Then more proactive solutions to internet security will be discussed, including the implementation of security plans, detection systems, and other hardware and software solutions that help automate security.
For many years firewalls were thought to be the core of good security. ... In addition, internal employees and business partners can penetrate firewall security by using backdoors or stolen administration passwords. Most monetary losses from security are attributed to such “insiders” who have access to internal systems. ... Firewalls are essential tools, but they are not the core of internet security. Organizations should instead focus on a layered, holistic security architecture. Such an architecture recognizes that a correctly installed and configured firewall is only a stepping stone on the road to an effective security strategy. Another critical step is the adoption of a formal security policy.
Organizations are realizing that there is more to internet security than firewalls, and they are starting to add intrusion detection systems (IDS) to their arsenal. ... Whenever any one of these IDS components spots a potential security threat – a virus or an impending hacker attack (for example) - it notifies a central management console. If a security threat is severe, the system automatically pages IT staff, who can deal with the attack by cutting off access, reconfiguring their systems, and even identifying the source of the attack and notifying the proper authorities. ... An intrusion detection system can detect these stealth scans, complementing the firewall and providing an added layer of security.
