What Is Cybersecurity?

Cybersecurity refers to all the technologies, tools, methods, and processes used to protect data, networks, and computer systems from unauthorized access by cyber attackers.

The main goal of Cybersecurity is to protect organizational digital assets from internal and external threats caused by natural disasters or hackers.

The three principles of Cybersecurity include confidentiality, integrity, and availability.

These three principles are the pillar of Cybersecurity.

Confidentiality asserts that the only individuals that can access functions and sensitive information are those allowed to.

With confidentiality, some users are blocked from accessing information.

Integrity is about ensuring that data is accurate, authentic, and safeguarded.

That means only authorized people can add, alter or remove functions or sensitive information.

Lastly, availability asserts that information must be made available to authorized parties whenever needed.

Through these three pillars, organizations can develop a robust Cybersecurity framework that helps reduce the risk of cyberattacks.

And in the unfortunate event that it happens, the business can get back to its feet without major losses.

Components of Cybersecurity

Three elements of Cybersecurity work together to ensure a strong defense against cyber attacks.

People

The employees of an organization must understand the principles of Cybersecurity, the risks involved, and how they minimize these risks.

Employees must understand the importance of using a strong password, backing up data, avoiding clicking links, and opening unusual email attachments.

Processes

Organizations must have a solid framework that guides their Cybersecurity approach in case of an attempted or successful cyber attack.

This involves having a framework that helps detect, identify, and respond to threats.

The framework should also have a guideline on how to recover from attacks.

Part of the process is having mitigation measures for potential attacks.

Technology

The technology involves the security tools to protect the systems and devices from cyber attacks.

Some of the technologies that protect smart devices, computers, and routers include email security solutions, malware protection, antivirus protection, firewalls, and DNS filtering.

These three components of Cybersecurity work together to avert cyber threats and attacks.

Types of Cybersecurity

Technology is growing rapidly.

Finance, hospitals, retail, military, energy, education, and different sectors are increasingly adopting new software at a staggering rate.

That means more information is stored online and can only be accessed through wired and wireless communication networks.

The sensitive information online lures criminals, making it of utmost importance to secure this information ‌to protect it from data breaches.

There are several sub-domains of Cybersecurity that help organizations stay safe against attack.

Here are the main types of Cybersecurity;

Network Security

Network security involves the software and hardware used to protect internal computer networks and infrastructure from authorized access, disruptions, intruders, misuse, and other abusers.

Organizations increasingly use complex networks, which increases devices, data, location, and users’ vulnerability.

Network Security is a type of Cybersecurity software that protects internal computer networks and infrastructure from authorized access

And so, organizations use network security tools such as Virtual Private Networks (VPNs), firewalls, antivirus, and anti-malware to protect their systems and networks from internal and external threats.

Again, strong network security prevents downtime and reduces potential vulnerabilities.

Cloud Security

Cloud security helps companies using cloud service providers like Azure, Amazon, Google, web services, AWS, and Rackspace to protect their information stored in the clouds.

Application Security

Application security involves securing web and mobile applications.

Usually, security in applications is installed during the development stage to ensure it is secured before being released in the market to reduce vulnerability.

Once it’s released, patches and updates may reinforce the security further.

Using application security, organizations can test apps and detect any threats in good time, which makes it easier to protect them further using encryption.

Critical Infrastructure Security

Critical infrastructure organizations are more susceptible to cyber-attacks.

Thus, to ensure the essential infrastructure services have a buffer against cybercriminals, they must have organizational and technical measures in place to avert any cyber threats.

Internet of Things (IoT) Security

Internet of Things includes electric and electronic devices such as motor vehicles, refrigerators, washing machines, smart fire alarms, thermostats, and light bulbs, among other things, that connect to the internet directly without human intervention.

Smart devices are increasingly at risk, given the opportunities offered by the Internet of Things.

And so, IoT security involves putting measures in place to ensure these devices are safe.

Disaster Recovery and Business Continuing Planning

Apart from cyber criminals, disasters or other natural events can compromise an organization’s information security.

In such circumstances, sensitive data must be protected to ensure business continuity after the disaster.

That means organizations need a plan to back-up data in case of any eventualities.

User Education

User Education is about educating employees on the monitoring, processes involved in case of an attack, and the plans they can take to respond.

Here employees are educated on computer security, the best practices in the industry, organizational policies and procedures, and reporting any malicious activities threatening operations or data loss.

Types of Cybersecurity Threats

Individuals and organizations face several threats, including:

Malware

Malicious software includes ransomware, trojan horse, botnets, virus, spyware, and adware.

Though the different types of malware are used differently, the bottom line is that attackers use malware to gain access to an organization’s network and transfer data from its storage.

Malware also disrupts computer systems and blocks access to computer resources.

Phishing

A phishing attack is a form of social engineering where attackers send fraudulent links, texts, or emails that seem to come from reputable companies.

A phishing attack is a type of Cybersecurity threat where attackers send fraudulent links, texts, or emails that seem to come from reputable companies

The messages usually ask for sensitive information such as login details, credit card data, etc.

Phishing is the most common type of cyberattack.

SQL Injection

Structure query language (SQL) injection is about launching an attack by inserting a malicious code to explore an SQL server’s vulnerability.

If attackers find a vulnerable point, an SQL injection can affect all the websites that use the codes.

Denial-of-Service (DoS) Attack

Denial-of-Service is where attackers flood a network, computer, or server with traffic to prevent users from accessing them.

Disgruntled employees often launch these attacks.

But sometimes, the attack is financially motivated.

Sometimes attackers may use DoS to make a service unavailable.

DoS is using multiple machines or computers to flood a network or server and hinder access.

Man-In-The-Middle Attack (MITM)

A man-in-the-middle attack‌ is where an attacker poses as a third party in the middle of two users and intercepts the communication.

MITM’s primary goal is to steal users’ information.

Attackers may pose as employees to steal data or even launch bots that generate fake messages.

Brute Force

Hackers use brute force to get login information, encryption keys, passwords, and Personal Identification Numbers (PINs).

Attackers will guess possible combinations until they find the right one to hack the systems and steal data.

Challenges Facing Cybersecurity

Cyber threats pose huge challenges to Cybersecurity as the rate of cyber-attacks keeps increasing.

Big and small companies are at risk of losing sensitive information, which not only disrupts their service delivery but also damages their reputation.

Here are the factors that increase the risk of cyber attacks.

Rapidly Evolving Risks

Information technology is ever-evolving.

Technology that was powerful ten years ago is currently obsolete.

The ever-evolving technology is a breeding ground for new attacks as many organizations find it challenging to keep up with the new tech updates.

Even smaller organizations without an IT department may find it challenging to keep up.

High-Speed Internet

High-speed internet makes it easy to change data in real time.

An increase in bandwidth translates to high-speed internet, which is great but threatens an organization’s information systems.

That means cyber attackers can also upload loads of data online, compromising data security.

Remote Working

With the pandemic, more and more employees were working from home.

Some employees use public Wi-Fi when traveling, which can be risky because they may connect to rogue hotspots, licking crucial company information to cyber attackers.

The collection of large quantities of confidential data is one of the challenges facing Cybersecurity

Further, remote work increases the risk of losing devices that may contain company information.

For that reason, the increased rate of remote work increases organizations’ risk of cyber attacks.

Collection of Large Quantities of Confidential Data

The more information an organization has to store, the more risk they are of a cyber criminal breaching and stealing their data.

Even small organizations tend to accumulate sensitive customer information in months.

Bring Your Own Device (BYOD)

Bring Your Own Device policy is an excellent way to reduce the cost of devices that the organization acquires.

However, employees using their own devices introduces a new set of Cybersecurity risks.

Employee-owned devices are more susceptible to cyber attacks, as the devices are not subject to the same security measures as organization-owned devices.

Organized-State Sponsored Hacker Groups

Hackers are increasingly becoming more organized and systematic in their operations.

There are different groups of hackers.

 Some are dedicated to cyberterrorism, others to cyber warfare, while many are committed to cyber espionage.

Given how organized they are, the rate of cybercrime is increasing, and so is the magnitude.

Conclusion

Cybersecurity protects individuals’ and organizations’ data from cyber threats and attacks.

Organizations can choose one or several types of Cybersecurity to ensure their data is safe depending on their devices, systems, and networks.

A well-devised Cybersecurity framework allows organizations to identify threats and act on them in record time before jeopardizing their operations.

In essence, a cyberattack is an ever-present threat to digital information.

For that reason, the importance of Cybersecurity cannot be underestimated in modern times.

It’s better to take action now.
