Computer Network Defense (CND) is a format of cybersecurity used to protect both government and military computer systems. Like other systems worldwide, national agencies must also secure their systems against cyberattacks.
We live in a highly technological age that includes computers and other technologies being utilized to benefit people all over the globe. Computers allow people to make innovative products for everyone to delight in. Computers enable people to create stories, write video clips, or create thrilling new things online, including video games and websites.
Positive Technology of Security in Computer Network
As with every other positive technology in the world, computers can also commit crimes such as hacking into corporate networks and even accessing customer data and intellectual property. The hackers have done this for years, even before the advent of the internet, which has forced web admins and companies to change their security procedures in line with changing technology.
Around the globe, military and government agencies utilize computers to defend their systems and safeguard their national security by preventing hackers from accessing critical systems. CND and the intelligence community can help keep vital infrastructure and other crucial national systems secure from hackers who want to harm them.
What are the Challenges with Computer Network?
Indeed, hackers and those looking to use technology to gain will not go away. In the face of this constant threat, many new threats are presented each year for cybersecurity professionals who must ensure that security is maintained for companies and individuals who depend on their ongoing operations and for government agencies.
New cyber security professionals must adapt to and overcome the challenges presented by these challenges. The most crucial aspect of the computer network’s defense is adjusting to new threats and challenges that arise. This is why an effective incident-response strategy that is clearly defined in terms of security protocols is of crucial importance to security professionals worldwide.
These are only some of the problems that continue to be a problem for security professionals to this day:
Malware. Malware Basically is “malicious software,” and it’s everywhere. Hackers employ a variety of malware to accomplish one of their evil goals in the entire spectrum. It doesn’t matter if they are trying to hack into a company network, steal customer secrete data or take over a website and gain authority to restrict accounts and data. Ransomware is a kind of malware that can encrypt desktop and notebook computers and require a fee to decrypt them. Remote access trojans may be able to remain in systems for a long time and later take them over, giving hackers the kind of control it would be able to have in the case of in front of a keyboard.
Humans. As we all know, humans are the most significant vulnerability for any security system. Computer networks are highly secure, but those who manage and utilize them aren’t invincible and vulnerable to human errors. If a hacker can influence users to visit a shady hyperlink or install infected software, they could gain entry into the computer. Human vulnerability is the primary reason every business (especially government agencies) must make cybersecurity an essential aspect to educate all employees. If employees are educated about the security practices of their company and procedures, they will be less likely to fall into the trap of hacking.
Phishing. Phishing(and spear Phishing) remains one of the primary methods hackers use to get into secure systems. All you need is an email that appears to originate from an essential individual in the company. An employee who isn’t aware may follow a hyperlink or download malware in an email. It’s all it takes to allow hackers access to systems and cause enormous damage.
Finances. The truth is that many businesses don’t have enough money for their security system. Companies need to establish a solid budget for a security program that educates everyone (not only security professionals) about the necessity of suitable security methods. Some organizations fail to get funding for a good cybersecurity program until they’ve suffered an incident of hacking or data loss.
These are a few issues that CND is facing today. They are among the most significant and persistent problems in the ever-changing sea of digital threats growing in recent years. Being aware of the issues you face with your CND strategy will allow you to adjust it and improve it as new challenges arise. This is why security experts need to keep an eye on new threats appearing in the news every year.
Best Practices with Computer Network Defence
There are proven strategies to ensure that CND strategies are solid for all organizations. Following these guidelines is the most effective method to ensure that your network remains safe from hackers and others who have malicious intentions.
Utilize a firewall. One of the initial and best security measures your network has is the use of a firewall. A firewall is an obstacle between your company’s essential data and those seeking to take it. Firewalls add layers of protection to the security layers already in place. In addition, your assets may not permanently reside behind corporate firewalls. Therefore, it’s essential to know what your assets are doing when they’re not in the firewall.
Visibility. Being able to see and understand your entire network is crucial in the present. It is essential to know the type of traffic currently in your network, whether it should be present and how long it has been there? Additionally, you must have adequate visibility into the cloud services that you currently use, Office 365, Google Gmail and Salesforce.com, to mention some. Awareness and knowledge of who has access to your systems, what they’re there, and if they are the person using those systems. If they’re not your desired user, you must be immediately alerted. This type of security is a requirement in the present technological environment.
Write down and describe your security practices. Every plan, including incident response to the various strategies for different attacks, is written and clearly outlined. This will aid in the evaluation of CND methods and also help adapt the security policy to new issues that may arise as time passes. A solid and flexible approach for security is among the most effective ways businesses can ensure their systems remain secure and airtight.
Have a plan for mobile devices. If your business depends on mobile devices like tablets, smartphones, and laptops, you must be prepared to support these devices too. Make a list of who gets what machine, and make sure that each device is updated with the most current versions of software and security updates. Mobile devices can correct through their apps or settings based on the operating system they’re running. Search for updates to Google’s Android through Google Play Protect on the Google Play Store or via your Android setting of the system. iPhone apps for Apple can update via the Apple App Store, and system updates can be applied using the iPhone settings in the system by clicking “Check for Updates.”
Inform employees about the importance of best practices in cybersecurity. Assuring that staff members are informed of your company’s security policies. This will ensure that staff members aren’t deceived by phishing scams and click on links that aren’t trustworthy or install malware-laden files on their computers.
