What Is Cybersecurity, and Its Types


Cybersecurity is the practice of deploying people, policies, procedures, and technologies to protect organizations, their critical systems, and sensitive information from digital attacks.

What Does Cybersecurity Mean for Your Business?

Cybersecurity is a business problem that has been presented in boardrooms for years, and accountability still primarily rests with IT leaders.

In the survey, 88% of board members classified cyber security as a business risk in 2022 for Gartner’s board of directors; Only 12% called it a technology risk. Still, a 2021 survey showed that the CIO, chief information security officer (CISO), or their equivalent, was held accountable for cyber security in 85% of organizations.

Organizations have become more vulnerable to cyber threats as digital information and technology are now heavily integrated into day-to-day work. But the attacks themselves, which target both information and critical infrastructure, are becoming far more sophisticated.

Cyber-risk events can have operational, financial, reputational, and strategic consequences for an organization, all of which come at significant costs. This means most organizations need to step up their cyber security game and has made existing measures less effective

What Are the Cybersecurity Concerns for Critical Infrastructure?

Important infrastructure sectors include energy generation and transmission, water and wastewater, health care and food, and agriculture. In many countries, critical infrastructure is owned by the state, while in others, the U.S. Like the U.S., private industry owns and operates the vast majority of it.

Each of these areas is not only vital to the proper functioning of modern societies, but they are also interdependent, and a cyber attack on one can have direct effects on others. Attackers are increasingly opting for cyber-physical systems (CPS) attacks

The risks were very real, even before Russia invaded Ukraine, Attacks on organizations in critical infrastructure sectors increased from less than 10 in 2013 to nearly 400 in 2020, an increase of 3,900%. It should come as no surprise, then, that governments around the world are mandating greater security controls for mission-critical CPS.

The Russian invasion of Ukraine has increased the risk of cyber attacks for all organizations. You need to develop a holistic, coordinated CPS protection strategy, incorporating emerging protection directives into governance for critical infrastructure. For example, the US “National Security Memorandum on Improving Cybersecurity for Critical Infrastructure Control Systems” is prioritizing the power and natural gas pipeline sectors, followed by the water/wastewater and chemical sectors.

The crux of the problem is that traditional network-centric, point-solution security tools are simply not enough to combat the speed and complexity of today’s cyber attacks. This is especially the case as operational technology (OT), which connects, monitors, and secures industrial operations (machines), converges with the technology backbone that processes an organization’s information technology (IT). continues to do so.

Prepare a complete inventory of OT/Internet of Things (IoT) security solutions in use within your organization. Also, evaluate standalone or multifunction platform-based protection options to further accelerate CPS protection stack convergence.

What Is a Cyberattack?

Some of the most common and notable types of cyber security attacks include

  • Phishing and Social-Engineering-based attacks.

Attackers trick legitimate users with the proper access credentials into taking actions that open the door to unauthorized users, allowing them to transfer information and data out (data exfiltration).

  • Internet-facing service vulnerability (including cloud services).

These threats relate to the failure of enterprises, partners, and vendors to adequately secure cloud services or other Internet-facing services (for example, configuration management failure) from known threats.

  • Accounts-related to passwords are compromised.

Unauthorized users deploy software or other hacking techniques to identify common and reused passwords that they may use to gain access to confidential systems, data, or assets.

  • Misuse of Information.

Authorized Users unintentionally or intentionally transmit or otherwise misuse information or data to which they have lawful access.

  • Network-related and Man-in-the-middle attacks.

Attackers may be able to monitor unsecured network traffic or redirect or intercept traffic resulting from a failure to encrypt messages in and out of an organization’s firewall.

  • Attack on the supply chain.

Partners, vendors, or other third-party assets or systems (or code) become compromised, creating a vector to attack or extort information from enterprise systems.

  • Denial-of-Service Attack (DoS).

The attackers overwhelm enterprise systems and cause a temporary shutdown or slowdown. Distributed DoS (DDoS) attacks also flood systems but use networks of devices. (See also “What Is a DDoS Attack?”)

  • ransomware

Restricts access to encrypted data or systems This malicious software infects an organization’s systems until a ransom is paid to the perpetrator. Some attackers threaten to release the data if the ransom is not paid.

What Is a DDoS Attack?


Cyber attackers deploy DDoS attacks by using a network of devices to overwhelm enterprise systems. While this form of cyberattack is capable of shutting down service, most attacks are actually designed to cause disruption rather than completely disrupt service.

Thousands of DDoS attacks are now reported each day, and most are downplayed as the normal course of business with no specific attention paid to them. But cyber attackers have been able to broaden the scope of the attack – and DDoS attacks continue to grow in complexity, volume, and frequency. This presents a growing threat to the network security of most small enterprises.

DDoS attacks are also increasingly directly targeting applications. Successful and cost-effective defending against this type of threat, therefore, requires a multipronged approach:

Internal: Security inside your network, behind the firewall.

Edge: On-premises solutions (enterprise firewalls and physical devices on or in front of edge routers)

External/cloud provider: Outside the enterprise, such as an Internet service provider (ISP)

People and Process: Include the incident response and mitigation playbooks along with the skill sets needed to prevent an attack

DDoS mitigation requires different skills than those required to defend against other types of cyber attacks, so most organizations will need to enhance their capabilities with third-party solutions.

What Are Cybersecurity Controls and Cyber Defense?

A series of IT and information systems control areas form the technical line of defense against cyberattacks. Includes:

Network and Perimeter Security.

A network perimeter demarcates the boundary between an organization’s intranet and the outside or public-facing Internet. The vulnerabilities pose a risk that attackers could use to attack resources connected to the Internet.

Endpoint Protection.

 Endpoints are devices connected to the network, such as laptops, mobile phones, and servers. Endpoint security protects these assets and, by extension, the data, information, or assets associated with these assets from malicious actors or campaigns.

application security.

Both cloud-based and traditional, before and after applications are deployed, it protects the data or code within the applications,

data security.

It includes the processes and associated equipment that protect sensitive information assets, either in transit or at rest. Data protection methods include encryption, which ensures sensitive data is erased, and creating data backups.

identity and access management (IAM).

IAM enables the right people to access the right resources for the right reasons at the right time.

zero trust architecture.

It removes the implicit trust (“This user is inside my security perimeter”) (“This user is authenticated with multi-factor authentication from a corporate laptop”) and replaces it with an adaptive, explicit trust working security suite” Is”).

Technology controls are not the only line of defense against cyberattacks. Leading organizations critically examine their cyber-risk culture and the maturity of relevant functions to expand their cyber security. This involves building employee awareness and safe behavior.

Why Does Cybersecurity Fail?


Simply put, cyber security fails because of a lack of adequate controls. No organization is 100% safe, and organizations cannot control threats or bad actors. control inputs, the organization only prioritizes security readiness

Benchmark your security capabilities – for people, process, and technology – and identify gaps to fill and prioritize goals to decide where, when, and how to invest in IT controls and cyber defense.

Notably, the human element is heavily involved in cyber security risks. Cybercriminals have become experts at social engineering, and they use increasingly sophisticated techniques to trick employees into clicking malicious links. It’s important to make sure employees have the knowledge and information to better defend against these attacks.

What Is the Future of Cybersecurity?

The environment itself is evolving in a number of key ways:

  • The increasing complexity of networks, infrastructure, and architecture creates a greater number and different types of connections that can be targets of cyber-attacks.
  • The growing sophistication of threats and poor understanding of the threat has made it difficult to keep track of the growing number of information security controls, requirements, and threats.
  • Third-party vulnerabilities will persist as organizations continue to struggle to establish minimal but strong controls for third parties – especially as most vendors, especially cloud vendors, are increasingly relying on third parties themselves (which is your fourth-party security). become parties and so on).
  • Cybersecurity debt has grown to unprecedented levels as new digital initiatives, often based in public clouds, are deployed before security issues are addressed.
  • Cyber-physical systems are designed to orchestrate sensing, computation, control, networking, and analysis in order to interact with the physical world (including humans). Connecting the digital and physical worlds (in the form of smart buildings) presents a unique and growing area of vulnerability.
