Digital Network Security System explained
The way we live our lives professionally and socially has been transformed by computer technology. Nearly all organizations have a computer network to store, receive and send information. Security is a key component of computer usage.
Security is a top priority for networks that contain sensitive, confidential or personal information. A digital network security system is required for even simple computer use, such as the storage and exchange of email messages.
Secure Systems are important
Both large and small government agencies need to ensure their network security. If a security buffer is breached, intruders could cause significant damage to a network. These concerns require that all computer network users are aware of their surroundings Broadcom panama .
If hackers are to be stopped, computer security systems must be updated regularly. Every day brings its own security problems. The International Journal of Electronic Security and Digital Forensics 2010 Vol. 3 security threats are being created every day on the Internet, according to the International Journal of Electronic Security and Digital Forensics (IJESDF) 2010 Vol.
* Deterrence is the first area of focus. This is the goal of deterrence.
* Prevention: Put in place measures to prevent unauthorized access. This can be achieved by communication encryption, security system updates and authorizing special access.
* Detection and resolution of security incidents as they occur. This is achieved by setting up logs that track access to the system and its usage.
* Correcting system flaws. You can use the security system to implement measures to prevent the flaw from reoccurring.
* The National Institute of Standards and Technology (NIST) identifies four main goals for network attackers. One of these goals might be pursued by an attacker in a network:
* Intercept: An attack on a system in which an attacker attempts to gain unauthorized access. This could be information copying, packet sniffing, or communication eavesdropping.
* Interrupt: This is a technique that attempts to prevent the provision of services. This causes resources to become unavailable.
* Fabrication: This attack is known as counterfeiting. Fabrication attacks can lead to the bypassing of authenticity controls, which ultimately leads to information impersonation or mimicking.
Modification: This attack redirects information meant for a specific user.
The last cyber attack that digital network security system analysts must deal with is active attacks and passive attacks. These can be either active or passive attacks. Because they cause system disruption, active attacks are easy to spot. They take the form:
*Masquerade- Impersonation of an authorized User
Passive attacks are difficult to detect because they don't alter or disrupt information flow. They can be described as traffic analysis or transmission monitoring.
