Network security combines multiple facets of defenses that implement policies and controls, which ensure that only authorized users gain access to network resources. Every business and organization, regardless of its size and industry, requires some level of network security in place to protect it from impending cyber attacks.
As you begin taking the necessary steps to ensure that your network is secure, there are three phases in which you’ll go through.
- Protection: Making sure that your network systems are configured correctly.
- Detection: Identifying when any configurations have changed, or when network traffic indicates a problem.
- Reaction: When a problem is identified, responding quickly so that your network can respond to its safe state as soon as possible.
Digitization has transformed our world. How we live, work, play, and learn have all changed. Every organization that wants to deliver the services that customers and employees demand must protect its network. Network security also helps you protect proprietary information from attack. Ultimately it protects your reputation.
How to improve knowledge skills
IPS technologies can detect or prevent network security attacks such as brute force attacks, Denial of Service (DoS) attacks and exploits of known vulnerabilities. A vulnerability is a weakness for instance in a software system and an exploit is an attack that leverages that vulnerability to gain control of that system. When an exploit is announced, there is often a window of opportunity for attackers to exploit that vulnerability before the security patch is applied. An Intrusion Prevention System can be used in these cases to quickly block these attacks.
The positive power of Network Security
To ensure that potential attackers cannot infiltrate your network, comprehensive access control policies need to be in place for both users and devices. Network access control (NAC) can be set at the most granular level. For example, you could grant administrators full access to the network but deny access to specific confidential folders or prevent their personal devices from joining the network.
