Cyber security is the practice of implementing people, policies, procedures, and technologies to protect organizations, their critical systems, and sensitive information from digital attacks.
What does cyber security mean to your business?
Cybersecurity is a business issue that has been presented in boardrooms for years, and the responsibility still rests primarily with IT managers.
In the survey, 88% of board members ranked cybersecurity as a 2022 business risk for Gartner’s board; Only 12% called it a technological risk. Yet a 2021 survey found that the CIO, Chief Information Security Officer (CISO), or their equivalent, was held accountable for cybersecurity in 85% of organizations.
Organizations have become more vulnerable to cyber threats as digital information and technology are now heavily integrated into daily work. But the attacks themselves, which target both information and critical infrastructure, are becoming far more sophisticated.
Cyber risk incidents can have operational, financial, reputational, and strategic implications for an organization, all of which have 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?
Key infrastructure sectors include energy generation and transmission, water and wastewater, healthcare and food, and agriculture. In many countries, critical infrastructure is owned by the government, while in others, the United States Like the United States, private industry owns and operates the vast majority of it.
Each of these areas is not only essential 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 choosing 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, a 3,900% increase. It should therefore come as no surprise that governments around the world are demanding greater security controls for mission-critical CPS.
The Russian invasion of Ukraine has increased the risk of cyber attacks for all organizations. You must develop a holistic, coordinated CPS protection strategy that incorporates new protection directives in the management of critical infrastructure. For example, the US “National Security Memorandum on Improving Cybersecurity for Critical Infrastructure Control Systems” prioritizes the energy 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 cyberattacks. This is especially the case as operational technology (OT), which connects, monitors, and secures industrial operations (machinery), converges with the technological 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 in your organization. Also, evaluate stand-alone or cross-platform protection options to further accelerate CPS protection stack convergence.
What is a cyber attack?
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 correct access credentials into taking actions that open the door for unauthorized users to transfer information and data out (data exfiltration).
- Internet-facing service vulnerability (including cloud services).
These threats relate to the failure of companies, partners, and vendors to secure cloud services or other Internet-facing services (eg, configuration management errors) 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 can use to gain access to confidential systems, data, or assets.
Authorized users transfer or otherwise misuse information or data to which they have lawful access, inadvertently or knowingly.
- Network-related and Man-in-the-middle attacks.
Attackers may be able to monitor unsecured network traffic or redirect or intercept traffic as a result of a failure to encrypt messages in and out of an organization’s firewall.
- Attack on the supply chain.
Partners, suppliers, or other third-party assets or systems (or code) are compromised, creating a vector to attack or extort information from enterprise systems.
- Denial-of-Service Attack (DoS).
The attackers overwhelm the company’s 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?”)
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. Although this type of cyber attack is capable of shutting down the service, most attacks are actually designed to cause disruption rather than completely disrupt the service.
Thousands of DDoS attacks are now reported every day, and most are downplayed as the normal course of business without much attention being paid to them. But cyber attackers have been able to expand the scope of the attack – and DDoS attacks continue to grow in complexity, volume, and frequency. This poses a growing threat to the network security of most small businesses.
DDoS attacks are also increasingly targeting applications. Successful and cost-effective defense against this type of threat, therefore, requires a multi-pronged approach:
Internal: Security inside your network, behind the firewall.
Edge: On-premises solutions (corporate firewalls and physical devices on or in front of edge routers)
External/cloud provider: Outside the company, such as an Internet Service Provider (ISP)
People and process: Include the incident response and remediation 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 Cyber Security Controls and Cyber Defense?
A number of IT and Information system control areas form the technical line of defense against cyber attacks. Includes:
Network and perimeter security.
A network perimeter demarcates the boundary between an organization’s intranet and the external or public-facing Internet. The vulnerabilities pose a risk that attackers can 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 those assets, from malicious actors or campaigns.
application security.
Both cloud-based and traditional, before and after applications are deployed, it protects data or code in the applications,
data security.
It includes processes and associated equipment that protect sensitive information assets, either in transit or at rest. Data protection methods include encryption, which ensures that sensitive data is deleted and creates backup copies of data.
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 within my security perimeter”) (“This user is authenticated with multi-factor authentication from a corporate laptop”) and replaces it with an adaptive, explicit, trust-functioning security package”Er”).
Technological controls are not the only line of defense against cyber attacks. Leading organizations are critically examining their cyber risk culture and the maturity of relevant functions to extend their cyber security. This involves building employee awareness and safe behavior.
Why Cyber Security Fails?
Simply put, cyber security fails due to a lack of adequate controls. No organization is 100% secure and organizations cannot control threats or bad actors. control input, the organization prioritizes only security preparedness
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.
In particular, the human element is heavily involved in cyber security risks. Cybercriminals have become experts at social engineering, using increasingly sophisticated techniques to trick employees into clicking on malicious links. It is important to ensure that employees have the knowledge and information to better defend themselves against these attacks.
What is the future of cyber security?
The environment itself develops in a number of important ways:
- The increasing complexity of networks, infrastructure, and architecture creates a greater number and different types of connections that can be targets of cyberattacks.
- The growing sophistication of threats and poor understanding of the threat has made it difficult to keep track of the increasing number of information security controls, requirements, and threats.
- Third-Party Vulnerabilities will continue as organizations continue to struggle to establish minimal but strong controls for third parties – especially as most vendors, especially cloud vendors, increasingly rely on third parties themselves (which is your fourth-party security). become parties and so on).
- Cyber Security Debt has grown to unprecedented levels as new digital initiatives, often based in public clouds, are implemented before security issues are resolved.
- Cyber-Physical Systems are designed to orchestrate sensing, computation, control, networking, and analysis 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.
