Is the Data of Your Company Secure?
Are you worried that you company’s data might not be secure? Here are a few facts you need to know about investing in the best intrusion detection systems, enterprise firewalls, and intrusion prevention systems before you decide which option is best for you.
An intrusion detection system, or IDS, is a device or software application that monitors network or system activities for malicious activities or policy violations and produces reports to a management station. Some systems may attempt to stop an intrusion attempt but this is neither required nor expected of a monitoring system. Intrusion detection and prevention systems (IDPS) are primarily focused on identifying possible incidents, logging information about them, and reporting attempts. In addition, organizations use IDPSes for other purposes, such as identifying problems with security policies, documenting existing threats and deterring individuals from violating security policies. IDPSes have become a necessary addition to the security infrastructure of nearly every organization.
In October, 2011, an international hacker broke into computer files at the South Carolina Department of Revenue, gaining access to about 3.6 million tax returns. The best intrusion detection systems bypass detection by creating different states on the IDS and on the targeted computer. The adversary accomplishes this by manipulating either the attack itself or the network traffic that contains the attack.
A statistical anomaly-based IDS determines what is normal network activity – like what sort of bandwidth is generally used, what protocols are used, what ports and devices generally connect to each other – and alerts the administrator or user, when anomalous traffic is detected. example: Suppose suddenly an exponential increase in TCP connection from 20 to 200.
In July 2008, a disgruntled San Francisco city administrator locked access to a critical network by resetting administrative passwords to its switches and routers and then refusing to divulge them to officials.
The next-generation firewall (NGFW) and how it is getting more sophisticated, as the threats to computer networks also increase in sophistication. If you are thinking about investing in the best intrusion detection systems, you should know that the price for firewall software can range from a few hundred dollars to many thousands of dollars. Though it might seem like a lot of money, spending this now will be significantly less than the issues that could arise as a result of a serious security breach. Get more here: www.sourcefire.com
