Malware infected damages and attacks continue to propagate through global networks, which has become the attackers’ most preferred and effective methodology for launching and propagating malicious applications for nefarious needs. The threats range from sniffing network traffic to ransomware attacks, and the direst of consequences involve outright damage to infrastructure and loss of data integrity. Though endpoint solutions have become sophisticated over the years, it is essential, especially for enterprises – small and big – and government organizations to opt for all-round protection schemes that gives them a greater chance to cover their bases.
Endpoint solutions for web security should necessarily incorporate expert recommended protection schemes into a single dashboard of sorts to give system administrators a strong handle on the overall security situation. Some of these methods are discussed:
- SIGNATURE-BASED ANTI-MALWAREMONITORING
Solutions should support numerous such scanners which can run simultaneously and reduce time for malware detection. Adaptive scanning is a novel feature that works by intelligently selecting scanners on web reputation score, content type, catch rate etc.
- ADVANCED PERSISTENT THREATS (APTs)
Endpoint solutions, especially Advanced Malware Protection (AMP) schemes protect systems from APTs by constantly scanning for suspicious activities on the network. This also includes assistance from knowledge base from around the world. Analysis of infected code includes behavioral indicators, network activity, process, registry etc.
- MALWARE PROPAGATION
AMP continues to monitor data on network and keeps tabs on it by recording its activities, its source, time it entered the network along with other relevant information. In case a threat is later tied to it, a complete initial investigative analysis can be sent to experts for further processing. Resultantly, this action stems the malware propagation by its early and timely identification, thus allowing for remedial or quarantine actions before damage is inflicted.
- COGNITIVE THREAT ANALYTICS (CTA)
This is a cloud-based solution by CISCO that reduces the discovery time of threats already operating inside the network. This security layer is established through behavioral and anomaly detection.
- WEB REPUTATION BLOCKS
This is another innovative process by CISCO that includes analyses of 50 parameters such as behavior and characteristics of a web server. Web addresses are scored on a scale of -10 to +10, and usually, all URLs with a score of less than -6 are blocked. AMPs can then scan the rest of the traffic outside the range.
- URL CATEGORIES
Categorizing URLs can help analyze the type of traffic and bandwidth consumed by each category. Not only does it come in handy from an administrative perspective but is also immensely helpful to keep an eye out for suspicious behavior which usually consumes more bandwidth.
- APPLICATION VISIBILITY CONTROL
This strategy can help administrators to control the myriad of Web 2.0 applications by adopting a granular policy which can control application specific functions of web pages. For instance, browsing may be allowed, but uploads may be blocked to secure network against a perceived threat of communication of malware with its command and control center. It also allows tracking of file sharing applications and number of files shared.
