The first line of defense against hackers and other cyber dangers is network security. Given projections that cybercrime would cost $6 trillion in worldwide damage by 2021, it’s easy to see why network security has grown increasingly vital. However, just as there are several types of assaults, there is a bewildering assortment of cybersecurity credentials from which to select.
While having so many cybersecurity options is undoubtedly beneficial, the sheer quantity and range of options also present a difficulty. It’s easy to become overwhelmed by the number of options available, to the point where you don’t make a decision at all. What are the most important network security credentials? Which one(s) is/are the best fit for you and your company? Is there any globally applicable cybersecurity certification?
What is Network Security?
Most experts describe network security as rules and methods for preventing trespassing, unlawful access, alteration, misuse, change, destruction, or the unauthorized collecting and distribution of data on network infrastructure. A mix of hardware devices, security software, and user understanding of security processes and approaches is required for the entire process.
Employees who have been educated on correct security procedures, as well as experts who have completed network security training, are examples of the latter aspect.
Why is Network Security Needed?
Many elements of our lives have made the transition to the digital realm. We utilize the internet to conduct financial transactions, interact with family and coworkers, shop, enjoy ourselves, and conduct research. Everything from birth dates, Social Security (or other identification numbers), health history, credit history, bank accounts, utility bills, and a variety of other things may be found online.
Hackers and fraudsters have access to all of that information and transactions. The more time we devote to the internet, the greater the chance of being hacked. Furthermore, as the Internet of Things (IoT) grows in prominence, so does reliance on wireless networks, which further adds to the dangerous environment by offering thieves more routes and opportunities to commit fraud. Network security is just too important in our personal and professional life to be jeopardized. So, what are the different forms of network security?
What Are the Types of Network Security?
Cybersecurity experts have access to a vast array of network security technologies, methodologies, and practices. Here’s a high-level summary:
Anti-virus, anti-malware, and anti-spyware are examples of security software. These tools are offered as suites or as subscriptions, and the hosting provider updates them regularly to stay on top of the current threats. These programs keep an eye on your network and stop intruders, spyware, and viruses.
Aside from that, it’s far better to acquire a security subscription rather than buying a suite and installing it yourself. Subscription providers/vendors are better equipped to deal with the cybersecurity landscape’s continuous changes. Every day, it seems like a new cyber danger or virus emerges, and your software won’t be able to protect you from risks it isn’t aware of. That’s why it’s best to let the subscription provider handle the heavy job.
This is such a basic precaution, yet it is crucial. Strong passwords are a low-cost but effective approach to keep systems, apps, and networks secure, and you don’t need to be a cybersecurity expert to use them. We don’t mean passwords like “password” or “123456789” when we mention “strong” passwords.
If your network were a posh nightclub, the firewall would be the bouncer, guarding the entrance and keeping intruders out. They block unwanted users by filtering traffic (both incoming and outgoing) according to preset criteria. Anyone who has attempted to work remotely but been kept out of their company’s core systems due to a lack of authorization knows how powerful a firewall can be.
Email Security Software
In any network, email is a highly vulnerable point. Cybercriminals like sending phony emails that appear to be from genuine businesses and financial institutions. However, a single click on a link included in these phishing emails might infect your machine. To that purpose, email security software may not only filter out incoming threats but can also block the transmission of specific types of data.
This method classifies and splits traffic according to predetermined parameters. Segmented networks are particularly helpful for confining users to a single region, namely the one in which they need to conduct their work while keeping them away from material that isn’t relevant to them. Restricting users in this way helps to reduce the network’s overall weak points.
Which Network Security Certifications are the Best?
Before you can make a lot of money in network security, you must first master the tools and abilities. This is where network security education comes into play. Cybersecurity training certification courses not only provide you with the necessary information for these roles, but they also provide you with a useful credential that verifies your qualifications to potential employers.
CEH: Certified Ethical Hacker
The IT security specialists, sometimes known as “white hat hackers,” have the responsibility to try to infiltrate systems and identify flaws. They are hired by businesses and organizations to discover flaws in the system and figure out how to repair them. When you consider how essential cybersecurity has become, it’s no surprise that this certification is so valuable.
CISSP: Certified Information Systems Security Professional
This cybersecurity certification is for experienced security professionals who are in charge of developing and managing security processes, policies, and standards for their business. It is ideal for IT security professionals who are looking to further their careers.
CISM: Certified Information Security Manager
This certification is essential for IT professionals who are responsible for enterprise-level security management. They are in charge of managing, developing, and overseeing security systems, as well as developing organizational best practices.
CCSP: Certified Cloud Security Professional
Because many businesses are progressively shifting to the cloud, this certification is in great demand. The course is designed for IS and IT professionals who want to learn about cloud security architecture, design, operations, and service orchestration best practices. This is a must-have if you work with cloud platforms.
There is no better approach for an IT professional to become well-rounded than to gradually obtain cybersecurity analyst certification. Even the most seasoned cybersecurity experts might benefit from a refresher course. Whether it’s a newly found cyber danger or a new technique to combat it, there’s always something new to learn. Upskilling not only elevates your status inside your company. But also makes you a more marketable candidate if you decide to move on. Expertise, leverage, and flexibility are all benefits of upskilling.
