Today's cyber security industry is primarily focused on protecting devices and systems from attackers. While the bits and bytes behind these efforts can be hard to visualize, it's much easier to consider the effects. Without cyber security professionals working tirelessly, many websites would be nearly impossible to enjoy due to ever-present denial-of-service attack attempts. Imagine not having access to Simplilearn's community of experts and certified professionals — no more tips, tricks, and advice to help you achieve your professional goals!

Without solid cyber security defenses, it would be easy to destroy modern-day essentials like the power grids and water treatment facilities that keep the world running smoothly.

Simply put, cyber security is critically important because it helps to preserve the lifestyles we have come to know and enjoy.

CIA Triad
The security of any organization starts with three principles: Confidentiality, Integrity, Availability. This is called as CIA, which has served as the industry standard for computer security since the time of first mainframes.

Confidentiality: The principles of confidentiality assert that only authorized parties can access sensitive information and functions. Example: military secrets.
Integrity: The principles of integrity assert that only authorized people and means can alter, add, or remove sensitive information and functions. Example: a user entering incorrect data into the database.
Availability: The principles of availability assert that systems, functions, and data must be available on-demand according to agreed-upon parameters based on levels of service.
Who is a Cyber Security Expert?
As data breaches, hacking, and cybercrime reach new heights, companies are increasingly relying on Cyber Security experts to identify potential threats and protect valuable data. It makes sense that the Cyber Security market is expected to grow from $152 billion in 2018 to $248 billion by 2023.

So what do Cyber Security experts do? On any given day, they:

Find, test, and repair weaknesses within a company's infrastructure.
Monitor systems for malicious content
Identify network breaches
Install regular software updates, firewalls, and antivirus protection
Strengthen areas where attacks may have occurred
They work in one or more of these common Cyber Security domains to keep data safe:

Asset security: Analyze networks, computers, routers, and wireless access points
Security architecture and engineering: Standardize security policies and procedures
Communication and network security: Regulate cloud storage and data transfer
Identity and access management: Track user authentication and accountability
Security operations: Monitor security to identify attacks
Security assessment and testing: Test security policies to ensure compliance with industry standards
Software development security: Create and repeatedly test code
Security and risk management: Identify potential risks and implement appropriate security controls
Cyber Security experts employ different tactics to secure computer systems and networks. Some of the best practices include:

Using two-way authentication
Securing passwords
Installing regular updates
Running antivirus software
Using firewalls to disable unwanted services
Avoiding phishing scams
Employing cryptography, or encryption
Securing domain name servers, or DNS
