A cyberattack involves a purposeful attempt to illicitly penetrate a network, computer system, or digital device with the intention of stealing, exposing, altering, disabling, or destroying data, applications, or other valuable assets.
How does a Cyber Attack take place?
Numerous cyber attacks are opportunistic, as hackers identify weaknesses in the defense mechanisms of a computer system and take advantage of them. This could entail identifying vulnerabilities in a website’s code and enabling the insertion of their code to bypass security or authentication procedures.
Alternatively, it may involve the installation of ’malware,’ a type of software explicitly created to harm a system, through a susceptible third-party site.
Different Types of Cyber Attacks?
Malware:
Malware, short for malicious software, refers to any intentionally crafted program or code designed to inflict harm upon a computer, server, or network. It is the most prevalent form of cyberattack, encompassing various subsets like ransomware, trojans, spyware, viruses, worms, keyloggers, and any other instance where software is utilized maliciously.
Phishing:
Phishing is a cyberattack that employs various methods, including email, SMS, phone, social media, and social engineering, to lure a target into disclosing sensitive information like passwords, account numbers, and other personal information. Another tactic involves convincing the victim to download a harmful file that installs viruses on their computer or phone.
Denial-of-Service (DoS) Attacks:
Denial-of-Service (DoS) Attacks flood a network with fraudulent requests, disrupting regular operations. During such attacks, users face difficulty accessing email, websites, and online accounts. While typically not resulting in data loss and often resolved without ransom payment, DoS attacks strain organizations, demanding time and resources for restoration.
Spoofing:
Spoofing is a method in which a cybercriminal conceals their identity by posing as a recognized or trusted entity. Through this deceptive tactic, the adversary can interact with the target, gaining access to their systems or devices with the primary objective of pilfering information, extorting money, or introducing malware or other malicious software onto the device.
Cyber Attack Preventive Measures
We recommend following the essential strategies listed below to safeguard a Small and Medium Business or organization against cyber attacks.
Multi-Factor Authentication:
Boost cybersecurity by enabling multi-factor authentication for all organization applications accessing the internet. Depending solely on passwords leaves systems vulnerable to compromise through hacking or phishing. Multi-factor authentication requires employees to provide multiple pieces of information, significantly heightening security and making unauthorized access more challenging.
Third-Party Security:
To prevent cyber attacks, managing third-party cyber risk responsibly is crucial. Understand the duties related to third-party security, especially if vendors or third parties access the organizational system. Implementing strict security controls, identifying cyber threats, and vigilant network monitoring are essential for system security.
Educate the organization’s Staff:
Educating employees enhances business security. Conduct cybersecurity awareness training during employee onboarding, with additional sessions at regular intervals. Annual training ensures that the entire staff is versed in safeguarding against security threats. Educating all employees on phishing is crucial, making them discern regular requests from suspicious ones in emails and other communications. This approach establishes a more secure overall business environment.
Create Data Backups:
Regularly backing up essential business data is crucial for maintaining business continuity. This preventive measure is vital to avoid worst-case scenarios involving the loss of critical business data. Consistent data backups ensure that the business remains resilient despite unforeseen events, minimizing the risk of total data loss.
Maintain System Updates:
Regularly updating systems and business software is crucial for robust business protection. Using the latest software enhances data security and ensures long-term resilience. Despite potential inconveniences, frequent updates are essential to address new issues and vulnerabilities in business software, guarding against security threats. While updates may incur costs, the benefits usually outweigh the expenses.
Deploy Antivirus Software and Firewall:
Preventing security breaches and cyber-attacks requires installing antivirus software. Each organizational computer should have updated antivirus protection, and a firewall should always be in place.
How to Detect a Cyber Attack?
While it’s impractical to prevent cyberattack attempts completely, organizations can use continuous security monitoring and early detection procedures to recognize and signal ongoing cyberattacks.
• Security information and event management systems centralize and monitor alerts generated by diverse internal cybersecurity tools, including intrusion detection systems (IDSs), endpoint detection and response systems (EDRs), and other security solutions.
• Threat intelligence platforms like Cyble Vision enhance security alerts, aiding security teams in comprehending the various types of cybersecurity threats they might encounter.
• Antivirus software that routinely scans computer systems for malicious programs and automatically eliminates identified malware.
• Proactive threat-hunting procedures designed to uncover cyber threats concealed within the network, such as advanced persistent threats (APTs).
How to Respond to a Cyber Attack?
Organizations can also take measures to appropriately respond to ongoing cyberattacks and other cybersecurity events. This includes:
Implementing incident response plans assists in containing and eliminating various types of cyberattacks, restoring affected systems, and analyzing root causes to prevent future attacks. Incident response plans have proven to reduce the overall costs associated with cyberattacks.
The use of Security Orchestration, Automation, and Response (SOAR) solutions enables security teams to coordinate various security tools through partially or fully automated playbooks, facilitating real-time responses to cyberattacks.
Adopting Extended Detection and Response (XDR) solutions, which integrate security tools and operations across all security layers, encompassing users, endpoints, email, applications, networks, cloud workloads, and data. XDRs facilitate the automation of complex cyberattack prevention, detection, investigation, and response processes, including proactive threat hunting.
Examples of Cyber Attack
Cyberattacks encompass a wide range of tactics, and examples include:
Malware:
Malware, a portmanteau of ”malicious software,” refers to intentionally designed software created to inflict harm or exploit systems. This category encompasses viruses, worms, trojans, ransomware, and spyware.
Phishing:
Engaging in deceptive tactics to acquire sensitive information, like passwords or financial details, by posing as a reliable entity in electronic communication.
Distributed Denial-of-Service (DDoS) Attacks:
Overwhelming a system, network, or website with traffic disrupts its normal functioning.
SQL Injection:
Taking advantage of vulnerabilities in a website’s database through the injection of malicious SQL code, intending to gain unauthorized access or manipulate data.
Credential Stuffing:
Gaining unauthorized access to a website by utilizing stolen username and password combinations from one platform where the user has recycled the same login credentials.
Zero-Day Exploits:
Targeting vulnerabilities in software or systems that are not yet known to the vendor or have not been patched.
Social Engineering:
Manipulating individuals to disclose confidential information through psychological manipulation or deceit.
These examples highlight cyber attackers’ diverse methods to compromise systems, steal data, or disrupt operations. Individuals and organizations must stay vigilant and implement robust cybersecurity measures to mitigate these threats.
