What is Cyber Security?
Cyber security is the practice of protecting computers, servers, mobile devices, electronic systems, networks, and data from all kinds of malicious attacks. More commonly referred to as information technology security or electronic information security, the term lends its application across business-to-mobile computing to a few common categories.
Network Security: Network security is the process that involves protecting a computer network from intruders, which can be maliciously targeted attackers or opportunistic malware.
Application security: Application security primarily focuses on keeping software and devices free of threats. A compromised application could provide immediate, direct access to the data it is intended to protect. Security starts in design, long before a program or device is ever fielded.
Information security: Information security protects the integrity and privacy of data, both in storage and in transit.
Operational security: Operational security encompasses methods and policies for the handling and protection of data assets. In turn, the access permissions users have when entering a network and the procedures that dictate how and where data can be stored or shared all fall within this category.
Why Cybersecurity is important?
Cyber attacks and cybercrime have the power to disrupt, damage, or destroy businesses, communities, and lives, in terms of importance. Successful cyberattacks lead to identity theft, personal and corporate extortion, loss of sensitive information and business-critical data, temporary business outages, lost business and lost customers, and in some cases, business closures.
Cyberattacks exert massive and increasing effects on businesses and the economy at large. For example, one estimate is that cybercrime will cost the world economy USD 10.5 trillion per year by 2025. The cost of cyberattacks increases as cybercriminals become continually sophisticated.
Types of cybersecurity
Comprehensive cybersecurity strategies protect all of an organization’s IT infrastructure layers against cyberthreats and cybercrime. Some of the most important cybersecurity domains include:
AI security
AI security refers to the measures and technologies designed to prevent or mitigate cyber attacks and threats targeting AI applications or systems, or those systems applying AI to malicious operations.
Generative AI is a new source of attack vectors that threat actors can exploit. The hackers can use malicious prompts to manipulate AI apps and poison data sources for distorting the output of AI. In fact, they can also force AI tools to reveal sensitive information. Furthermore, they can make use of-and are already doing so-generative AI as a source of malicious code and phishing emails.
AI security uses specialized risk management frameworks—and increasingly, AI-enabled cybersecurity tools—to protect the AI attack surface. As indicated in the Cost of a Data Breach 2024 Report, the average cost per breach was USD 2.2 million less for those organizations that extensively deployed AI-enabled security tools and automation for cyberthreat prevention compared to organizations that did not use any AI at all.
Critical infrastructure security
Critical infrastructure security protects computer systems, applications, networks, data, and digital assets on which a society depends for national security, economic health, and public safety.
In the United States, There are multiple sources of information pertaining to cyber security frameworks to protect critical infrastructure. The National Institute of Standards and Technology, NIST, offers an IT security framework to help providers and other stakeholders secure their infrastructures.5 Another source is the US Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency, CISA.
Network security
Network security deals with the protection of networks and their resources against unauthorized access. It also ensures access by authorized users to the needed resources and assets securely and reliably so that they can perform their jobs.
Application security
Application security prevents an application and related data from being accessed or used illegally. It helps identify flaws or vulnerabilities in the design of the applications and mitigate their impact. The modern application development methods have been enhanced to include technologies such as DevOps and DevSecOps, which build security and security testing into the development process.
Cloud security
Cloud security relates to securing an organization’s cloud-based services and assets, which may comprise applications, data, virtual servers, and other infrastructure.
Quite simply, cloud security is based on the concept of shared responsibility. It is the responsibility of the cloud provider to make sure the services that it provides are secure and also the infrastructure delivering that service. However, that said, the customer alone is responsible for ensuring its own code, data, or other assets that it maintains or executes in the cloud are secure.
Information security and data security
Information security, or InfoSec, is the protection of an organization’s important information — digital files and data, paper documents, physical media — against unauthorized access, use, or alteration.
Data security is essentially the subsection of information security, and most of the InfoSec, which focuses on cybersecurity, deals with data security.
Mobile Security
Mobile security is smartphone and mobile devices-specific security tools and practices for cybersecurity, including mobile application management (MAM) and enterprise mobility management (EMM).
With the advent of the modern version of unified endpoint management (UEM) solution, its focus today is more targeted since it protects, configures, and manages all endpoint devices from a single console.
