Why Information and Network Security are important

by Mic Johnson

Cybercrime is a huge industry, and we can expect hackers to step up their game. With all the data that modern companies and organizations keep, it’s safe to say that they’re targets for cybercriminals.

If, despite this, a company still is complacent with information and network security, regulations and policies will ensure user data is secure. 

A lot is at stake here. Banks, for instance, cannot be relaxed concerning their customers’ account details. We have heard of high profile cyber thefts such as the infamous Bangladesh Central Bank heist. On a much smaller scale, we’ve heard of instances where hundreds of dollars siphoned from a person’s savings account or an unidentified purchase happened in one’s credit card.

Security isn’t just a concern for nerds. It has significant implications for companies, organizations, governments, and individuals.

The Role of an IT Manager

In this regard, the IT Manager’s job is even more critical. To be more specific, the job title should be Information and Network Security Manager because they are in charge of keeping the company’s or organization’s information related assets secure from cyber threats.

This person is mainly responsible for ensuring that the company’s computer networks and information system are free from threats. This responsibility includes being on top of system upgrades and evaluating new security-related programs that can help the organization. The IT manager also makes sure that the IT services are managed well with his assistants and employees.

Like a general strengthening the defenses of a kingdom, the IT Manager also simulates possible attacks and sets up countermeasures against such. Moreover, he makes sure the company is compliant with all relevant policies.

Being in this role is exciting as it is unenviable. It is, therefore, important that the person in the job is well equipped, and his skills are updated.

Listed below are some of the most highly recommended Information and Network Security certifications for IT Managers.

Certified Ethical Hacker (CEH)

What it is

To beat hackers, you have to think like a hacker. This is what CEH allows you to do. As a “white hacker,” you will have the expertise to search for your system’s security vulnerabilities and attempt to exploit them. The intention of which is to figure out the best way to plug those security holes or, better yet, eliminate them.

The CEH is offered by the EC-Council (International Council of E-Commerce Consultants). 


The candidate should go through a 5-day training and pass the certification exam. This is for intermediate-level IT managers.
