IT security breaches are quite common in today’s complex world of hyper-scale IT systems. There are different cybersecurity best practices and a lot of such breaches occur around the world every day. Some are considered minor, with little loss of data or monetary value, but a lot of them are considered major, or even catastrophic for an enterprise.
Hackers who orchestrate such security breaches are continuously looking for new vulnerabilities in IT systems and networks that can easily be exploited. When networks are not secured, information about organizations and individuals, and even government agencies are at risk of being exposed to unwanted individuals or organizations.
And in order to face this challenge, information security analysts keep on developing and implementing security measures to protect an organization’s IT ecosystem and keep it clean from vulnerabilities.
What is network security?
Network security can be defined as the process of taking preventative actions in order to protect the underlying networking infrastructure from unauthorized access, misuse, malfunction, modification, destruction or improper disclosure that can be used to harm an organization or an enterprise ecosystem and its overall business operations.
Implementing these network security measures allows computers, users, programs and applications to perform their permitted critical functions within a secure and controlled environment.
Securing a network requires a complex combination of multiple set of hardware devices, such as routers, firewalls and anti-malware software applications that help organizations in the event of any breach in security.
And in order to ensure 24×7 security of their IT infrastructure – more and more government agencies and businesses are today employing highly skilled information security analysts to implement security plans and constantly monitor the efficacy of these plans.
Why is network security important for enterprise and government users?
Network security is quite important for home networks as well as business or enterprise network. Most homes with high-speed internet connections have one or more wireless routers and this could be easily exploited if not properly secured. And that is why a solid network security system ensures no data loss by theft or sabotage of IT systems.
Here are some simple steps you can take to secure a home network:
Regularly change your router admin username and password
Turn off guest networks
Update router firmware
Change the network name
Preventing Network Security Breaches at Your Workplace
In today’s data-intensive world, data equals cash and that is why we see so many high-profile enterprise and government related data breaches making headlines quite regularly.
These data breach attacks result in losses of millions of private records and sensitive information which can cost millions in damages to enterprise and government agencies.
What is a security breach?
A security breach could be anything ranging from unauthorized access or transfer of data or a data leakage to misuse of the network and computational resources at various levels.
Here are some of the steps you can take to prevent a security breach across your network.
Securing Your Router
Cybercriminals can easily compromise your data and simple vulnerabilities in routers can help them exploit on this and that is why it is extremely important to secure your routers. You can secure all the devices in your network by ensuring that encryption is enabled on your wireless traffic.
Identifying Breach and Managing Response
Whether it is a large enterprise with global operations or small and local oragnisation – it is very important to identify the security breach in a timely fashion. With the recent surge in activity of high-profile attacks targeting sensitive data assets, developing a data breach response plan in advance helps in triggering a quick response in the wake of breach incident.
Installing centralized firewalls
Firewalls are the first line of defense in any network security and hence firewalls become very important to be regularly updated and kept abreast with latest software capabilities that may help thwart any data breach. A suitably configured firewall acts as a barrier between networks with differing layer of trust. And this is why it is important to keep the local firewall on all the time as this is the best way you can arm your network against malicious attacks.
Enabling encrypted transmission of data can always help in its protection. Stolen encrypted data is of no value for cybercriminals. Cryptography is designed in such a way that it can restrict access to data and can render it useless to those who do not possess the key to open it.
And that is why security analysts always emphasize on using encrypted transmission of all critical data. Using encryption is a big step towards mitigating the damages of a security breach and can ensure security for your business and user critical data ecosystems. And hence, the safety and security of our society rests on our ability to protect confidential information from outside threats.
