Systems Security Devices To Guard Against Computer Crimes
Over the past two decades, computers and internet services have affected every single aspect of human life However, the very features of the technology that make it such a boon to the society are also susceptible to abuse.
Companies are now investing millions of dollars towards installation of network and system security devices that can protect against computer crimes. Some of the devices are listed below.
Intrusion Prevention Systems (IPS): These are used to monitor and alert whenever any suspicious activity or intrusion is detected in the system. IPS is also useful in detecting any application attacks that can affect the system behavior. However, this system cannot provide effective protection against attacks that target web applications.
Firewalls: Installation of firewall technology is important to control network traffic and protect against any suspicious intrusions or attacks on the network. Firewalls primarily function by allowing or blocking IP addresses and port numbers. However, firewalls are ineffective against attacks from worms, viruses and trojans.
Anti-virus software programs: These programs are designed to prevent any attacks of worms, viruses and trojans on the system or network. It is important to have these systems regularly updated so that they have provide complete protection against these bugs. However, the biggest disadvantage of anti-virus software programs is that they tend to occupy large memory space thereby reducing the efficiency of the system.
Security devices based on Biometrics: These devices rely on fingerprints, retinas and other personal traits in order to authenticate users. Although these are secured devices, it is possible for criminals to breach the security provided by them.
Unified Threat Management Device or UTM: This device provides an all-in-one security for the system performing functions like network firewall, intrusion detection and prevention, gateway virus scanning, filtering and controlling a wide variety of network communications and inspecting all network traffic. These devices are easy to install, use and maintain. However, the disadvantage is that if the system gets damaged then the entire security cordon on the system gets affected.
