What is an Intrusion Prevention System?
A type of network security called an intrusion prevention system (IPS) tries to identify threats and stop them from happening. Systems for preventing intrusions continuously scan your network for hostile activities and record information about them. The IPS notifies system administrators of these occurrences and takes corrective action, such as shutting down access points and setting up firewalls to block further intrusions. IPS systems can also spot corporate security guidelines' problems, discouraging staff members and network visitors from flouting their prohibitions.
A typical company network has a lot of access points, so it's crucial to have a technique to keep an eye out for indications of prospective offenses, incidents, and immediate threats. But, unfortunately, today's network dangers are getting increasingly complex, and they can get past even the most robust security measures.
IPS and IDS - What is the Difference?
Intrusion detection systems (IDS) may also be found when researching IPS solutions. However, before we examine the operation of intrusion prevention systems, let's examine the distinction between IPS and IDS.
The response that IPS and IDS provide when a possible event occurs is the primary distinction between them.
• Intrusion prevention systems regulate network access and guard against misuse and intrusion. These systems are made to keep track of intrusion data and take the appropriate steps to stop an attack from progressing.
• Intrusion detection systems are not intended to thwart attacks; instead, they only keep an eye on a network and warn system administrators when a potential threat is discovered.
How Do Intrusion Prevention Systems Work?
Systems for preventing intrusions operate by examining all network communication. An IPS is made to stop a variety of threats, including the following:
• DoS (denial-of-service) attack
• Attacks including Distributed Denial of Service (DDoS)
• A variety of exploits
• Worms
• Viruses
The IPS conducts real-time packet inspection, thoroughly examining each packet crossing the network. The IPS will take the following measures if any malicious or suspicious packages are found:
- Stop the exploited TCP session and prevent the offending source IP address or user account from accessing applications, target hosts, or other unethical network resources.
- Reprogram or reconfigure the firewall to stop an attack of this nature from happening again.
- If harmful content is left on the network after an attack, remove it or replace it. Repackaging payloads, deleting header data, and removing any contaminated attachments from file or email servers are used to accomplish this.
Trend Micro Intrusion Prevention
The Tipping Point Intrusion Prevention System from Trend Micro, a component of their XGen security solution, offers best-in-class intrusion prevention to defend against the full spectrum of cyber threats at wire speed and anywhere on your organization's network to safeguard your reputation and business-critical data. Trend Micro is aware that businesses are looking for efficient, flexible, all-encompassing protection that satisfies their hybrid networks' cybersecurity and performance requirements as cyber threats evolve alarmingly quickly and with greater sophistication. Their system defends your network from all types of attacks and cyber threats.
The Intrusion Prevention system module protects your computer from known and unknown security threats. For example, SQL injection attacks, cross-site scripting attacks, and other web application vulnerabilities. Rules for intrusion prevention can also stop traffic that exploits the security flaw when the operating system or software vulnerabilities are not patched.
It provides you with better visibility into the security of programs connected to the network and can detect dangerous malware connecting to it. Your PCs are therefore protected until updates to close the vulnerability are ready for testing and deployment. In addition, software for file-sharing and communications includes protection. e.g., Skype and web-based programs vulnerable to cross-site scripting and SQL injection (XSS). A light internet application firewall can also use for intrusion prevention (WAF).
