How Digital Transformation is Re-defining Home Security
Network attacks were assumed to be limited to organizations with sensitive data. This is no longer the case. Today, everyone who uses the internet needs to be wary of unprecedented attacks. The risk has been heightened with the introduction of smartphones and other portable devices. Companies now do most of their transactions online and have lots of data which need to be protected. A few years back, companies and individuals were concerned about viruses attacking their systems. However, additional protective features have become necessary, especially in this digital era. There are various intrusion detection systems with specific features designed to meet the network security needs of individuals and organizations.
An integrated Intrusion Detection System in Singapore is not easy to find. If you are looking for one, look for ATT Systems. They have a wide range of expertise and can advise you on your security needs. Visit their site today.
In this article, Richard Allen discusses the different intrusion detection systems and how enterprises can benefit from them.
Types of intrusion detection and prevention systems
“One of the many defense-in-depth strategies you should deploy to protect your enterprise from attacks and breaches involves intrusion detection and prevention. Originally sold as separate systems, most now have the capability to be deployed either way. Network Intrusion detection examines the packets that travel over a network and flags any suspicious traffic….” Read more here
Intrusion detection systems are either network based or host based. Network Intrusion Detection Systems (NIDS) monitor network traffic and warn of any suspicious activities. Host-based Intrusion Detection Systems (HIDS) use an agent to look out for any suspicious activity. HIDS are linked to a host computer. If you are wondering which of the two, HIDS or NIDS, is more important, none is. They are both essential. NIDS focuses on the traffic on your network and will report any suspicious activity while HIDS looks out for the files and data in your computer. Should there be an attempt to infiltrate the system, these intrusion detection systems will notify you.
In this article, Robert J Shimonski discusses components of intrusion detection systems and how they will be of benefit to individuals and organizations.
What you should expect from intrusion detection systems
“Firewalls and other simple boundary devices lack some degree of intelligence when it comes to observing, recognizing, and identifying attack signatures that may be present in the traffic they monitor and the log files they collect. Without sounding critical of such other systems’ capabilities, this deficiency explains why intrusion detection systems (often abbreviated IDS) …” Read more here
Intrusion detection systems are artificial intelligent software which can detect and analyze log files to see if there are any anomalies. This information is processed and stored. Should it find a similar signature in future, it will have a reason to be suspicious. It immediately sends a notification of its doubts. Sometimes, these intrusion detection systems go ahead and shut down links and servers in a bid to protect the system. The same mechanism is used in home and office security systems when wrong security codes are used in an attempt to gain entry. If this is done repeatedly, the intrusion detection system will react to secure the network.
In this article, Jonathan Lister discusses the pros and cons of using intrusion detection systems.
What you gain when you install intrusion detection systems
“Intrusion detection systems for computers provide comprehensive defense against identity theft, information mining, and network hacking. Big businesses and government agencies employ such software to keep information and accounts safe as well as monitor the network activities of employees to ensure on-site facilities are not being misused.” Read more here
It would be impossible to know the activities of all employees who have access to the network were it not for intrusion detection systems. Besides providing network security, intrusion detection systems play an essential role in boosting the productivity of the organization. Knowing that their activities are monitored will force employees to focus on their work. The intrusion detection systems also work round the clock as long as the system is connected to the network. You, therefore, need not worry about what happens when away from your computer.
The intrusion detection systems have been designed for customization. It can, therefore, be altered to suit the needs of every organization or individual. What is constant is its primary role in securing your information and data. As digitalization continues to improve accessibility to information, intrusion detection systems need to be used to reduce network vulnerability.
