Malware Security Testing Strategies for Enterprises
September 9, 2013
Thanks to Ankur Chadda for this guest post. Ankur is a product marketing manager at Spirent Communications which covers thesecurity and applications market segment to achieve technology solutions.
For most companies, propertesting of security measures is often overlooked or completely ignored. Therisk is great, with tens of thousands of malware strains introduced every day. Nearlyevery IT environment utilizes security systems to help detect and stop malware.These might include firewalls that can be configured with various rules, UTMsystems offering content filtering, gateway antivirus, and intrusion preventionsystems (IPS).
While various systems are used to spot and stop malware, such asfirewalls, gateway antivirus tools, intrusion prevention systems and deeppacket inspection, these solutions are themselves not frequently tested.Stopping the highest percentage of malware requires testing these solutionsunder high-scale realistic traffic conditions.
Challenges
- Bring Your Own Device (BYOD) policies introduce morecomplexity due to the risk of out-of-date security. Companies need to balanceworker’s demands with controlling company data.
- Sophistication of the attacks – malware criminals areutilizing mobile-based malware to commit fraud or gain personal data.
- Risky user behaviors such as bad password protection or frequentingquestionable sites.
Importanceof testing – And Best Practices
Finding the proper balance is vital between resources required to aggressivelystop malware and allow the organization and staff to operate withouthindrance. Testing allows IT to gauge strong or weak points in their defenses,so they can implement fixes instead of restricting access. A proven testmethodology follows PASS (performance, availability, security, and scalability).Thismethodology provides answers to several questions including how is user QoSaffected by latency, when devices fail do services also fail, and how manythreats can systems currently detect.
Gateways, firewalls and IDS should all be tested underscale so IT can judge if the systems can handle high amounts of traffic. Thetesting solution needs to produce both secure and insecure traffic and have thelatest malware definitions in order to best replicate real-worldconditions. IT departments thatproactively implement such solutions will be able to stop a higher percentageof threats while allowing the business to operate efficiently.
