Why Intrusion Detection and Intrusion Prevention Systems are Vital

Institutions, organizations and small businesses operate based on the data they have. It would be impossible to run such organizations if the available data was disrupted. Imagine what you would do if you woke up one morning and found your system hacked and vital information missing? It could take months or even years to recover from such a loss if at all it is possible to recover from it. Intrusion detection and prevention systems are designed to protect you and your business from such havoc. It encourages continuity and longevity of business by safeguarding information, especially confidential data.

In this article in lbmcinformationsecurity.com, the author discusses the functions of intrusion detection and intrusion prevention systems.

Why you need to use both intrusion detection and intrusion prevention systems

“Losing sensitive information because of a cyber-attack has been a concern for businesses and enterprises for nearly two decades.  In the early 2000s, intrusion detection systems (IDS) and intrusion prevention systems (IPS) became a security best practice to help businesses protect themselves against evolving data breaches. Before then, firewalls had been very effective in countering the threat landscape of the 1990s.” Read more here

If you are wondering if it is necessary to use both systems or if one can do, you need to ask yourself how important the data you have is to you as a person or how vital the information is to your company.  If you care about the security of your network and system, the intrusion detection and intrusion prevention systems are crucial. The intrusion detection system acts as a guard who alerts you if any suspicious activity is detected. The intrusion prevention system is placed between your firewall and your network. Should there be any anomalies, it immediately blocks access to your network.

In this article, Derek Wiedenhoeft discusses the consequences of not having intrusion detection systems.

Consequences of not using intrusion detection systems

“Should you invest in an Intrusion Detection System? Responsible businesses with sensitive data know they need a firewall to control traffic and secure their networks. What seems less well known, however, is the role that complementary technologies play in a comprehensive approach to cybersecurity.  An Intrusion Detection System (IDS) enables organizations to take a proactive security stance,…” Read more here

Unfortunately, once hackers realize that your system is vulnerable, they will attack more than once. This means you will be fighting one attack after another. Is this something you are prepared to face? What does one attack cost you and are you able to recover from several attacks? Cyber-attacks come with costs. Some of the attacks have financial implications, but the biggest challenge is your integrity. No client is willing to do business with an organization whose systems are vulnerable to constant cyber-attacks.  

In this article, Deb Shinder discusses the different approaches intrusion detection systems use and why you should not be comfortable if all you are using is a firewall.


Why your firewall is not enough to keep you safe

“In a perfect world, the only people who are accessing your network are people you know about and trust. You want vendors and clients to be able to access your network. You also want remote users to be able to access the network at night. But what about that guy sitting alone in his bedroom hyped up on caffeine and sugar with nothing better to do but to see what he can do to your network? Read more here

Although the firewall has some elements of intrusion detection, it is restricted in its functions. An intrusion detection system is designed to interpret and understand packet headers and not just focus on the IP address and ports. The widespread attention of the intrusion detection system gives it an edge over the firewall. This makes it more qualified to handle huge threats especially in organizations which have heavy traffic and sensitive data.

The cost of investing in intrusion detection systems is lower than the price of an attack on your system. The emotional turmoil that results from an attack and loss of vital data is immeasurable. Rather than take the risk, it is best to invest in the available intrusion detection systems for the sake of your business and your peace of mind.
