Any organization that relies on computer networks and the Internet must prioritize information security, but have you ever wondered what these procedures entail? This article will teach you everything you need to know about information security processes. We’ll show you what the information security processes are, the four types of information security processes, and the three components of information security.
Firstly, you will learn what information technology is and why it is important to learn. According to the Bureau of Labor Statistics, job growth in this in-demand field is expected to increase by 33 percent between 2020 and 2030. Learning about information security and its processes will help you stand out in the tech industry.
What Is Information Security?
Information security simply refers to the strategies, products, and procedures implemented by a technology expert to prevent unauthorized access or even insider threats to sensitive information. This data could be stored in the cloud or on physical storage devices. The IT security expert is responsible for ensuring that it is not disrupted or modified in any way.
There are three main types of information security specializations. These are physical security controls, management security, and operational security. Experts in these fields can work in any company with a network or an IT database, regardless of industry. Their job would simply be to protect a company’s digital assets by assessing the threat landscape and using secure applications to mitigate common information security risks.
What Are the Three Components of Information Security?
The three components of information security include confidentiality, integrity, and availability. They are collectively known as the CIA triad. The following section details the critical role each process plays in successfully executing information security processes.
Confidentiality
As the title implies, an application security expert must use computer encryption to ensure the confidentiality of sensitive data. Encrypted data can only be accessed by those with decryption keys or authorized users.
There are usually different levels of authorization within an organization. An IT security expert is responsible for ensuring authorized access within an organization and preventing data from being accessed from external sources.
Integrity
What is the quality of the data? Has it been compromised? Does it appear exactly how it was created? Can it be manipulated to suit a particular agenda? These are some of the questions you should answer when considering integrity as a component of security management.
An IT security expert ensures that data is not compromised during transmission or storage on the organization’s database. It is the backbone of security practices.
Availability
This is another vital component of information security. It is not enough for the information on the database to be free of security flaws and unaltered. It must also be available to authorized parties upon request.
The need for data availability varies greatly depending on the type of organization. For example, a hospital may place more significance on the availability of patient records than any other information on their data warehouse.
What Is an Information Security Process?
An information security process is a strategy or methodology designed to guide information security experts in carrying out their duties. There are certain requirements that must be met to protect an organization’s information technology infrastructure.
IT security processes extend beyond preventive measures to ensure data security. They also include a post-attack procedure or an incident response plan that is implemented in the event of a threat to a company’s IT network.
An IT security expert may specialize in preventing cyber security attacks, but what happens when a denial of service attack occurs or critical data is destroyed? This expert is also in charge of implementing strategies.
What Are Information Security Processes Good For?
IT security experts may be unable to perform their duties and responsibilities adequately without an information security process. Various actions must be carried out with caution to protect a company’s information technology systems. Some specific benefits of these processes are listed below.
- Risk Management. IT security policies are critical for risk management because they assist organizations in mitigating risk as efficiently as possible. An IT security expert performs a risk assessment on the IT infrastructure at regular intervals. They subsequently recommend technical changes that may reduce the level of risk and cyber threats.
- Compliance and Accountability. Have you ever wondered who protects the sensitive information you provide during registration, employment, school enrollment, or financial services? The information technology processes put in place by the IT security expert ensure that your data is not compromised in accordance with the company’s terms. These procedures ensure that the company remains compliant.
- Business Continuity Management. IT security processes are critical in developing a continuity plan for a business. They protect all critical functions of an organization from potentially crippling incidents. They include incident response plans and corrective actions that ensure business continuity in a major disruption in the IT department. According to ZipRecruiter, businesses pay IT security experts almost $150,000 annually.
What Are the Four Information Security Processes?
These are various processes, technologies, and strategies that comprise information security processes. However, these processes can be summarized in the four major categories listed below.
Password Management
Password management protects the most important process in information security. To protect data from security breaches both inside and outside the organization, an IT security expert must implement passwords and access rights. Passwords are decryption keys that provide various levels of in-person and remote access to people in the organization.
In large organizations, the clearance level and associated passwords are typically determined by hierarchy. As you advance through the levels, your security clearance increases, and you gain direct access to more data. As an agency information security officer, you’ll have to create a strong security culture and ensure that employees get a strong education in security topics such as password security.
Firewall Installation, Configuration, and Maintenance
A firewall is software or hardware designed to act as a barrier between information and unauthorized actors. It is the crown jewel of information security. A crucial information security process includes installing, configuring, and maintaining firewalls in an organization. An IT security expert must monitor these firewalls and note potential security issues.
A firewall thoroughly filters traffic in an organization’s network, ensuring and blocking all unauthorized access. Cyber attackers and other bad actors can easily exploit loopholes and virtually hijack networks without firewall application programming interfaces.
Penetration Testing
When an organization already has its firewall installed, the IT security expert can hack the network. The goal of this simulation is to determine whether the firewall is secure or if there are any vulnerabilities that bad actors could exploit. Penetration testing is an important type of ethical hacking because it allows a company to identify and fix security flaws before it’s too late.
Pen testers are security professionals who specialize in penetration testing. These penetration testers are trained in network security but specialize in ethical hacking. They could be part of the organization’s IT security team or independent contractors hired on a contract basis to hack the organization’s systems and report back to the company if a cyber risk is found.
Incident Response
What happens if a company’s database or any other information security system is breached? The incident management team steps in to save the situation with a disaster recovery plan. They put security strategies in place and recommend techniques or technologies to help an organization recover from a security incident.
There are seven steps of incidence response implemented by the security manager. They include preparing, identifying, containing, eradicating, restoring, learning, and testing. It is a continuous series of security techniques that are carried out in accordance with the company’s security goals.
How Can I Learn Information Security Processes in 2022?
You can learn information security processes in a university, information security bootcamp, or massive open online course. Your career objectives and financial capabilities will determine the path you take. If you are a recent high school graduate looking for a full college experience, you can pursue an information security degree.
Information security bootcamps are ideal for people who already have careers but want to switch to security. Courses are ideal for IT professionals who already have a basic understanding of computer science but need to learn about specific aspects of information security. You should weigh your options before you make a decision.
