25 Apr Portland IT Services Intrusion Detection System

One of the primary reasons why your company must hire the best Portland IT services in the world is to ensure that your Intrusion Detection System is optimized to the full extent of its capability. There is a need to protect your network from any cyber attack and you must do whatever it takes to shield your business against harmful intrusions from hackers who are always on the lookout for vulnerable networks to exploit. Do not make the same mistakes as other companies that take their network security for granted. Always keep in mind that once your system is compromised, it would be very hard to continue to function as if nothing happened. In fact, you would need to spend loads of money just to fix the remnants of the cyber attack on your network. And so to guarantee that there will be no unwelcomed intrusion to your network, you need to pay close attention to what is called Intrusion Detection System.

Intrusion Detection System Defined

The Intrusion Detection System or what is commonly referred to as IDS is actually a reliable and efficient system that observers the ongoing network traffic and monitors the network for any suspicious occurrence and problems. This software application has the responsibility to probe a network or a business system and scans them meticulously to check for any harmful activity, or an act of breach of network policies. Whenever there is a malicious intrusion, violation or other acts of anomaly in the network, the IDS reports to the administrator of the network, or this program collated all the data through the utilization of the SIEM  or security information and event management. And to manage the work of the IDS, you need a highly experience Portland IT services company to handle this task.

Also, the Intrusion Detection System must be properly tuned-in in order to avoid creating false alarms in the network. The program must be installed well and taught how to detect actual malicious activities, and determine what normal traffic is like, so it is not confused in its task for your network. And once the IDS is honed to the accurate detection of threats, it can work smoothly and efficiently and you or your IT support, or whoever is assigned to the network security of your company will be notified with legit threats and intrusions. And then your Portland IT services team can immediately do something to counter the attack and diffuse the situation.

5 Types of Intrusion Detection System

There are five different types of Intrusion Detection System, and they are classified as the following:

NIDS – Network Intrusion Detection System

The Network Intrusion Detection System is incorporated into the network in order to check the flow of traffic that comes from all the devices that is used within the company network. It examines the passing traffic and figures out if the traffic belongs to the same subnet of packets that is known as parts of known attacks, or are they similar to the network’s subnet. And when the NIDS detects a coming attack, the system notifies the network administration of the attack so the reliable Portland IT services that your company hired can provide a resolution immediately and prevent any more damage to your network. That is why it is relevant to have your own dedicated IT support in order to always be ready for what comes next. You never know when hackers attempt to penetrate your network by disguising their incoming traffic as legit and part of the pack.

HIDS – Host Intrusion Detection System

The Host Intrusion Detection System operates on independent devices or hosts that are part of that company network. They are tasked to observe the outgoing and incoming packets from the registered devices and if the system detects any form of malicious or mistrustful happenings, then the HIDS captures a snapshot and create a comparison with the older snapshots and see if they match. If the snapshots are not the same, then that means that the analytical system data was modified, and a notification is then delivered to the network administrator. And then the Portland IT services will do their job and investigate further what is going in.

PIDS – Protocol-based Intrusion Detection System

The Protocol-based Intrusion Detection System includes an agent or an individual system that frequently positions itself at the front section of the server and it expertly manages and construes the current protocol that exists between the server and the device or user that are part of the network. Its job is to safeguard the web server by observing the stream of HTTPS protocol and only accept the protocol that is related to the network’s HTTPS protocol in general. And your dedicated IT support can help you make sure that the said protocol is taken seriously, and the PIDS task is done efficiently.

APIDS – Application Protocol-based Intrusion Detection System

The Application Protocol-based Intrusion Detection System is an agent or a network’s system that is placed within the network’s servers, particularly belonging to groups. It is tasked to determine when an intrusion happens and interprets the data by comparison of particular protocols. This important responsibility is optimized by the help of a highly efficient Portland IT services team, and so you need to hire only the best in the industry. When the security of your company’s network is at stake, you need to invest in the experts in order to keep your business running smoothly.

Hybrid IDS – Hybrid Intrusion Detection System

The Hybrid Intrusion Detection System is the perfect blend of two, three, or more methods of the current intrusion detection system. In this program the system or agent works well with all the information provided by the network, and it is known to be much better at detecting intrusions compared to other forms of IDS. Your trustworthy Portland IT services play a huge part in the success of the Hybrid IDS, that’s why it’s crucial to hire the best.
