How to Prevent Cyber Attacks

There’s a lot of confusion and misinformation about cyber attacks and how they happen.

Any malicious attempt to compromise a computer’s systems is a cyber attack. Some of the ones you hear about are DoS attacks, which essentially consist of sending so many requests to a system that it’s overloaded in some way; phishing, which is using social engineering and tricks to steal passwords or sensitive information to break into systems; and hacking, which involves using various techniques to break into a computer system.

Importance of Cybersecurity

While personal computers can benefit from a good layer of cybersecurity, the bigger threat is to companies, organizations, and governments, especially on systems containing large amounts of personal information, financial assets, or other data that require privacy.

A successful cyber attack can gain access to any or all of this information, leading to massive financial loss, personal data leaks, and with it, damage to their reputation. Other attacks can also disrupt operations by shutting down servers or critical infrastructure.

That’s why it’s so important that organizations have strong cybersecurity measures in place to prevent damage from increasingly sophisticated threats.

Some Real-World Examples

The Colonial Pipeline ransomware attack in 2021 is a high-profile example that demonstrates how cyber incidents can occur through critical infrastructure, leading directly to fuel shortages across the Eastern United States.
Similarly, the SolarWinds breach of 2020 showed how supply chain attacks can cripple the logistics of thousands of organizations simultaneously. These are only some of the high-profile incidents, but many smaller ones are occurring all the time, underscoring the need for better cybersecurity measures everywhere.

Common Types of Cyber Attacks

Phishing Attacks: Phishing attacks are probably the most common form of cyber attack known to organizations and the most crucial to teach members how to protect against. The idea behind phishing attack prevention is that the attacker tries to exploit the ‘human element’ by posing as a legitimate entity that requires information about you – like your username, password, address, or other sensitive information. Using this information, they can bypass cybersecurity measures and gain access to the system. Modern phishing schemes have grown ever more clever, exploiting urgency, very legitimate-looking and sounding websites or messages, and other techniques such as zeroing in on specific individuals to trick them.
Malware and Ransomware: Insidious programs often come with decent software such as antivirus, office software and computer cleaning programs. They can also come from games, download links from just about anywhere online, or advertisements that pose as legitimate links. If you download one of these programs, you may often find hidden elements in deep crevices of your computer to encrypt and hold private data hostage. As with phishing techniques, malware protection has become more challenging as new techniques like polymorphic malware have come online.
Denial of Service (DoS) Attacks: DoS or (Distributed) DDoS attacks work by simply overwhelming a system with traffic, causing it to become non-functional to regular users. Bots especially make this possible, as a bot network can send thousands to hundreds of thousands of requests at the same time (it’s part of why captchas have to be a thing). Overall, the result can be the loss of revenue and customers when your systems are overloaded.
Man-in-the-Middle Attacks: These sophisticated attacks intercept communications between two parties. Sometimes, the security between two endpoints is easier to break than others, and some devices can ‘read’ the information through wires or wifi signals. Public WiFi networks are particularly vulnerable to such attacks, making encryption and secure communication protocols essential.
SQL Injection: SQL injection attacks exploit vulnerable database queries to access or manipulate data. These attacks can lead to unauthorized access to sensitive information, revealing just how important secure coding practices and input validation are.

Best Practices for Cyber Attack Prevention

Use Strong Passwords and Enable Two-Factor Authentication (2FA): The first line of defence in modern cybersecurity – strong password policies combined with 2FA help to solve most standard security vulnerabilities, especially against brute-force techniques. Passwords should be unique, complex, and regularly updated. Modern 2FA methods, including biometrics and hardware tokens, make it much harder for malicious agents to break in.
Regular Software Updates and Patch Management: Updates are extremely essential as they address the newest threats to a program’s software. Falling behind on updates can leave serious vulnerabilities in your systems.
Employee Training and Awareness: As previously mentioned, the human element can be one of the weakest leaks in the security chain. Even if a hacker can’t figure out a way to break into the software through sophisticated techniques, they may be able to exploit the people with access. That is why training to recognize phishing attempts, maintaining security hygiene, and understanding social engineering tactics are all important bulwark points to prevent a security breach.
Implementing a Firewall and Intrusion Detection System (IDS): Like the stone walls and watchtower of a castle, firewalls provide a basic layer of protection, while IDS systems provide an early warning system about suspicious activity. Modern versions are better than ever, with things like machine learning-enhanced IDS that can detect subtle attack patterns.
Data Backup and Disaster Recovery Plan: Regular backups following the 3-2-1 rule (three copies, two different media, one off-site) provide resilience against data loss. While successful attacks may still access the data, at least they will not be able to destroy it. Disaster recovery plans should be regularly tested and updated in your security hygiene routine.

Advanced Cybersecurity Measures

Network Segmentation: Implementing network segments and micro-segmentation limits the spread of attacks.
Zero Trust Architecture: Zero-trust network access principles bolster this approach by requiring verification for all connection attempts.
Encryption of Sensitive Data: Strong encryption protects data in transit and storage. End-to-end encryption is best where possible, maintaining strict key management practices.
Endpoint Security Solutions: Modern endpoint protection platforms help plug the gaps other security measures can’t, such as behavioural analysis, application control, and automated response capabilities.
Regular Security Audits and Penetration Testing: Proactive security testing helps identify vulnerabilities before attackers can exploit your information. While regular audits ensure compliance with industry standards.

Responding to a Cyber Attack: What to Do if Preventive Measures Fail

Step 1: Incident Response Plan: A well-documented incident response plan enables quick, coordinated action when attacks occur. It should define clear roles, responsibilities, and communication protocols.
Step 2: Isolating Affected Systems: Rapid isolation of compromised systems quarantines potential damage. Automated containment measures especially can help in the early stages of an incident.
Step 3: Notifying Authorities and Stakeholders: Proper incident reporting both fulfills legal obligations and keeps stakeholder trust.
Step 4: Forensic Analysis: After the incident, thorough incident analysis helps review what went right and wrong. This helps with future attacks and provides better evidence for legal proceedings.

The Role of Cyber Insurance

Cyber insurance is a way to obtain financial compensation when affected by a cyber security incident. Coverage is different for different cases and works much like other forms of insurance. Requires a certain level of assurance that you’re protecting your data and with different premiums for different levels of coverage.

Types of Cyber Insurance Coverage

Data Breach Protection: The most common and fundamental type of cyber insurance is Data Breach Protection. It helps your organization respond to and recover from cyber-attacks that affect your own data and systems.
Business Interruption Losses:Reimburses your business for lost income and extra expenses incurred due to a cyber-attack or data breach that disrupts your operations. Sometimes included in Data Breach Response insurance.
Technology Errors and Omissions (E&O): Specifically tailored for technology companies or companies providing technology-related services. E&O provides coverage for errors, omissions, or negligence when delivering those services that result in financial losses for clients.
Network Security Liability Network Security Liability protects your business if a third party (e.g., a customer, vendor, or business partner) sues you because a failure in your network security best practices allowed a cyber attack to impact them.
Privacy Liability: Similar to Network Security Liability, Privacy Liability focuses on claims of the unauthorized disclosure or loss of personally identifiable information (PII) and other confidential data.

Choosing the Right Policy

A good insurance broker or agent can help determine which policies make sense for your company. The risk profile of every organization is different, as are the preferences of stakeholders who may be more or less risk averse.
