Antivirus are softwares that are used for preventing, detecting, as well as removing malicious applications and softwares. Antivirus offers protection against browser hijackers, malicious BHOs (Browser Helper Objects), spyware, adware, fraudtools, malicious LSPs, Trojan horses, dialers, backdoors, keyloggers, rootkits, ransomware, and so on. Basically there are 2 types of scanning feature that antivirus comes with. The first one is complete system scan whereas the other is file scan. Complete scan feature will scan your entire system for malicious content. This is a time taking process. On the other hand, if you wish scanning few applications or files, you can make use of File Scan feature of antivirus. With file scan, all you need to do is browse the file that you want being scanned and click on scan option. This process takes less time when compared to full scan or complete scan.
Some of the best antivirus programs offering FileScan include Kaspersky anti-virus 2015, Avira, Avast, Bitdefender 2015, BullGuard, F-Secure, and many more.
Drawback of file scan antivirus
The biggest drawback that comes with file scan feature provided in most antivirus software is that here only single file can be scanned at a time which means if you have ten files to scan, you will be wasting time on browsing each file and clicking on scan option. Further, the entire system isn’t scanned which means virus, malware, or other malicious content is still present on the system and can affect you scanned file.
What is HIPS
HIPS is an intrusion detection system used for monitoring and analyzing internals of computing system in addition to network packets on network interfaces of it. In current environments there are ever-changing networks and system security defenders are continuously trying to keep pace as well as limit risks. Moreover, proactive security measure has become necessity. One of the highly effective proactive mitigation is HIPS (Host Intrusion Prevention System) implementation. Foundational goal in system and computer security is maintaining integrity and health of individual hosts; this is what defines HIPS. HIPS is an extremely valuable component that is used for defending system host integrity. HIPS are managed centrally in enterprise deployments and system administrator pushes rules and policies down for individual hosts. It will alert when there is some abnormal or malicious activity on hosts. Users can set HIPS policy to block/log suspicious or malicious activities. Generally, HIPS includes 4 varying technologies namely application or process behaviour monitor, file integrity monitor, registry monitor, and host firewall. All these four are defined below:
Host firewall – This will place barrier between external systems and computer. Every information that travels to and fro from the system will first pass via host firewall before it is fully processed. This firewall would carry out port-clocking and complete inspection on all incoming traffic to host. Only the important and used ports will be left open. Ports that aren’t used will be closed hence reducing risk of infections via unnecessary ports. Egress firewall is responsible for managing applications that should be permitted to send data from the host generally via whitelist hence reducing chances for malware and exploits to call back control servers and commands.
Registry monitor – Almost all information configurations for Windows system will be available in registry. Registry stores details about programs installed, options to pass, OS configurations, recently executed programs list, and so on. There are few monitors that will first take snapshot prior to scheduling running and compare current registry settings later with snapshots for identifying as well as alerting when unwanted changes are taking place. On the other hand, there are monitors that perform real-time registry protection by intercepting programs trying to perform unauthorized changes to registry.
File Integrity Monitor – It will report alert when there are changes to critical application and system files.
Application/Process Behaviour Monitor – It studies behaviour of processes running on system as well as alerts when some application tries attempting action that is not as per allowed or normal course of action.
Some of the best providers of HIPS application are Mcafee, ProcessGuard, etc. You can go for their free or paid version.
Drawbacks or considerations with HIPS
In order to get effective security system, it is vital that HIPS has well-defined as well as tuned set or rules and policies. There are vendors that offer several rules with their tool but still system administrator has to perform turning so that this system works perfect for their specific environment. If HIPS policy and rules aren’t set properly, this system becomes inefficient hence leading to system risks. In order to maximize effectiveness of HIPS, organizations require working towards manageable network prior. This means investment of time, money, and resource. At times, users may be required to manually tune HIPS system else it won’t work as per their expectations.
As the trend in antivirus job is changing or advancing, more and more malicious contents are being developed by hackers. This means antivirus and HIPS developers have to work more so as to design extra efficient programs for curbing ever increasing malicious contents. Moreover, scanning frequency and efficiency should be increased so that the process takes less time. These systems should be automated so that just by the click of a button scanning process starts without disrupting or affecting other running applications on the system. It has been seen that HIPS and antivirus when running on a system affects performance of other running applications. Hence, developers need concentrating on this area as well. Both HIPS and antivirus have their share of pros and cons so it is suggested to have both these tools on your system that in turn will give you better protection against malware, viruses, spyware, and so on.
We strongly recommend users choose top internet security software instead of single protection products, because they provide all-in-one protection including firewall, virus scanning, HIPS, anti-spyware, anti-phishing, and more, but with a comparative cost as single anti-virus or HIPS software.
