Cyber Security Attack Examples. FutureUniverseTV Shares Practical And In-Depth Understanding.
Through SafeOnline.org, the National Cyber Security Alliance recommends a top-down approach to cyber security that prioritizes cyber security management across all business practices. The National Cyber Security Alliance advises companies to be prepared to “respond to the inevitable cyber incident, restore normal operations, and ensure that the company assets and reputation are protected.”
As part of its guidelines for conducting cyber risk assessments, NCSA emphasizes three key elements: identifying your organization’s “crown jewels,” or the most valuable information that needs protection; identifying the threats and risks that threaten that information; and identifying the damage your organization would incur if the data was lost or improperly disclosed.
Additionally, cyber risk assessments should take into account any regulations that affect the way data is collected, stored, and secured, such as PCI-DSS, HIPAA, SOX, FISMA, etc. After performing a cyber risk assessment, develop and implement a plan to mitigate cyber risk, to protect the “crown jewels” identified in the assessment, and to detect and respond to security incidents effectively.
An effective cyber security program should include both the processes and technologies required for its implementation. An ever-evolving field, cyber security best practices must keep pace with attackers’ increasingly sophisticated attacks. Cyber criminals are most likely to gain access to sensitive information about your company if you combine sound cyber security measures with educated and security-minded employees. Despite the fact that it may seem like an overwhelming task, start small and focus on the most sensitive data, scaling up as your cyber program becomes more sophisticated.
What are some of the most common attack vectors? Weak or stolen credentials Ransomware Phishing Zero-Day Vulnerabilities Missing or inadequate encryption Misconfiguration Trust Relationships Brute force attack Distributed Denial of Service (DDoS) are common cyber attack vectors used by adversaries.
Is there such a thing as an attack surface? Your attack surface is represented by all of the points on your network where an adversary may attempt to access your information systems. In general, any technique that allows an individual to gain unauthorized access to a company’s data via any asset. For medium-sized and large-sized businesses, there can be a large attack surface. There are hundreds of thousands of assets that could potentially be targeted by hundreds of attack vectors, meaning that your attack surface is made up of tens of millions to hundreds of billions of signals that must be monitored at all times to uncover any potential threats. You can visualize your network as a graph with the x-axis listing all of the devices and applications (infrastructure, apps, endpoints, IoT, etc.) and the y-axis listing the different breach methods, including weak or default passwords, reused passwords, phishing, social engineering, unpatched software, and misconfigurations. Your attack surface is determined by your plot.
The purpose of a denial-of-service attack is to overwhelm the resources of a system so that it is incapable of responding to legitimate service requests. Similarly, a distributed denial-of-service (DDoS) attack seeks to drain a system’s resources. It is a DDoS attack in which an array of malware-infected host computers under the control of the attacker are used to launch the attack.
A “denial of service attack” occurs when a victim site is unable to provide service to users. In a DoS attack, the target site receives a flood of illegitimate requests. In order to respond to each request, the site has to consume a significant amount of resources. Due to this, it is impossible for the site to serve users as it normally would, which usually results in the site being completely shut down. Cyber attacks such as DoS and DDoS allow hackers to either gain access to a system or to increase their current level of access.
This type of attack directly benefits the attacker. The purpose of a DoS or DDoS network attack, on the other hand, is to interrupt the effectiveness of the target’s service. Depending on the circumstances, the attacker may be able to benefit financially from their efforts if they are employed by a competitor. It is also possible for a DoS attack to create a vulnerability that can be exploited by another type of attack. It is common for a successful DoS or DDoS attack to result in the system being taken offline, leaving it susceptible to other attacks in the future. Using a firewall to detect legitimate requests to your site is one of the most common ways to prevent DoS attacks. Therefore, imposter requests can be discarded, allowing normal traffic to continue uninterrupted.
