An IPS blocks known and unknown threats in real-time, protecting the network from attack and helping meet compliance requirements. IPS solutions can be standalone software applications, dedicated hardware devices, or cloud services. They sit in line on the network and work in tandem with firewalls.
Unlike traditional firewalls, IPSs are highly automated, freeing time for security teams. They also provide superior application security.
Detection Methods
The right IPS can help businesses protect technology infrastructure and sensitive data. It also helps them meet compliance regulations. In addition, IPSs provide security teams with a bird’s-eye view of network resources, which they use to modify systems when problems arise.
Unlike IDSs, which can alert administrators to potential cyberattacks but do nothing to stop them, IPSs take proactive steps to prevent attacks from happening. These include monitoring network traffic and analyzing suspicious patterns or behaviors. They can also detect if someone has accessed sensitive data or a system usually protected by a firewall.
Some IPSs use signature-based detection to monitor traffic for known attack patterns. They compare network packets against a database of preexisting signatures, and they can identify the exact threat and attack type being attempted. However, brand-new threats that still need to be analyzed for a signature can evade this type of detection.
Anomaly-based detection methods are more effective at identifying unknown threats. They create and continuously refine a baseline model of regular network activity and spring into action when an anomaly occurs. For example, they can detect if a device is using up more bandwidth than usual or if a process is communicating with a command-and-control channel that is usually encrypted or obfuscated. These IPSs are often infused with artificial intelligence and machine learning to reduce the false positives they produce.
What attacks are detected by an IPS? An Intrusion Prevention System (IPS) detects attacks by analyzing network traffic for malicious patterns and behaviors. Some of the most common attack types include Denial-of-Service (DoS) attacks and web application attacks, among others.
Scalability
In software, scalability describes the capacity of a system to adapt to increasing workload demands. This is important because it allows companies to grow without the cost and disruption of a drastic infrastructure transformation. It also helps reduce the time to market for new products and services. Regarding technical performance, scalability is measured by the latency, responsiveness, or error rate change as the number of end-users or external services increases.
An IPS network security solution monitors traffic and blocks malicious connections before reaching the destination. It is similar to an intrusion detection system (IDS) but offers much greater protection because it prevents attacks before they occur. It is an ideal choice for enterprise networks as it drastically reduces the risk of data breaches and downtime.
When choosing an IPS, consider its scalability and whether or not it supports a zero-downtime upgrade policy. This is important for businesses that need help to afford downtime during upgrades. A zero-downtime upgrade policy ensures that any changes made to the IPS will not cause downtime, allowing the IPS to scale seamlessly.
Another consideration is how many ports an IPS has and what type of interface it uses. For example, choose an IPS with dedicated IPs if your business sends large numbers of emails. Dedicated IPs offer better email deliverability and are essential for high-volume messaging. They are also more secure than shared IPs.
Customization
Unlike an intrusion detection system (IDS), which generates security alerts for IT personnel to investigate, an IPS can take action to block malicious traffic. This automation reduces enterprise cybersecurity risk by stopping malware and unauthorized users from embedding themselves in your network. There are several types of IPS solutions, including network-based and host-based. Network-based solutions are deployed at a network level and can detect traffic flowing to and from all connected devices. Host-based IPS solutions are installed on an individual endpoint and monitor only traffic to and from that point. Another option is a wireless intrusion prevention system (WIPS), which monitors the network for suspicious behavior on wireless networks.
Aside from their superior color accuracy, IPS monitors offer excellent response times and high refresh rates. These features make them ideal for graphic design, film editing, and other visual work. However, IPS panels are not the best choice for gaming, as they have more noticeable motion blur than TN monitors. This issue can be mitigated by choosing a monitor with a higher refresh rate or a lower response time.
While it isn’t entirely up to the ESP to decide who will share an IP, it is essential to ask the provider about their IP ranges’ current health and network state. If you’re mailing large emails, opting for a dedicated IP will help avoid reputation damage and deliverability problems.
Cost
An IPS is necessary for any enterprise cybersecurity strategy because it can close security holes left open by firewalls and block malicious traffic before it gets inside the network. This enables enterprises to minimize their cyberattack risk by reducing the number of threats that must be monitored and responded to manually.
An IPS can also reduce the workload of other security solutions by filtering out malicious traffic before it reaches them. This can increase their effectiveness and efficiency and free up valuable IT resources for other tasks. Moreover, an IPS can identify threats other systems cannot detect due to its ability to identify anomalies and suspicious behavior.
When choosing an IPS, you must determine what is most important to your organization. Its detection capabilities should be at the top of your list, but considering other characteristics is also a good idea. For example, choose an IPS with deep packet inspection capabilities and an intelligent threat prevention engine.
It would help if you also looked for an IPS with minimal false positives and low maintenance costs. It is also important to note that an IPS needs to be constantly updated to keep up with emerging attack campaigns. In addition, an IPS should be able to decrypt TLS-encrypted traffic streams efficiently without impacting performance.
