Prevent Cybersecurity attack: Guide to Cybersecurity Threats and Solutions

Introduction

Do you remember when the major types of cyber attacks broke out? It was in 2020— the Pandemic year. Since then there’s no going back. There has been a continuous rise in types of attacks in network security, impacting both individuals and businesses.

Data breaches between 2021 and 2023 rose 72%, surpassing all previous records. There were 343 million cyber attack victims worldwide in 2023, of which 300,000 were phishing attacks. The global recovery cost for data breaches stood at approximately $4.45 million states the “IBM’s cost of data breaches report”. United nation’s Internet Crime Complaint Center reported a historical peak of $12.5 billion in monetary damage during 2023.

This exponential growth in types of attacks in cyber security has risked the global economy and personnel safety. The World Economic Forum emphasizes an additional workforce of around 3.4 million cyber professionals to counter this turmoil, signifying massive opportunities in cyber security space. Cybersecurity jobs rose by 8.7% year on year during 2023 but still lag the required numbers to meet the growing types of cyber attacks.

This sounds alarming and signifies a critical need to adopt serious measures to prevent cyber attacks in cyber security. The path to defending against cyber attacks starts right from a common individual. Understanding the different types of cyber-attacks should be the utmost priority for personnel safety and this article is crafted meticulously to help individuals learn how to deal with this challenge.

Let’s begin this drive by understanding what is a cyber attack, first!

What is a Cyber Attack?

A cyber attack is a deliberate attempt to gain unauthorized access to personal or private data by intruding into a computer, network, or device. These attacks are executed illegally, often exploiting vulnerabilities in the system or its users to achieve goals such as stealing data, disrupting operations, or causing damage.

It can be done by an individual or a group depending on the scale of operation. People doing this crime are called “Cyber Criminals.” There can be several ways to attack an individual or a business over the Internet. The most common are sending phishing emails with scammy links, infecting a device or computer with malicious software, and intercepting communication between two parties to steal identity or some sensitive information.

People falling victim to cyber-attacks usually are unaware of the different types of cyber-attacks and ways to prevent these cyberattacks.

The Increasing Cyber Threat

Studies reveal the global cost of different types of cyber attacks can jump to around $24 trillion by 2027- a three-fold rise compared to the stats in 2022. Individuals and businesses combined face around 2220, on average, cyber-attacks daily. This risks the businesses, threatening their operational integrity and customer trust.

Financial firms are particularly at risk due to the sensitive data they handle and the frequent transactions they process. These institutions account for nearly one-fifth of all attacks.

Banks face unique vulnerabilities that could compromise financial stability if critical services are disrupted or confidence is eroded. Cyber incidents in this sector can lead to selloffs and runs on banks. For instance, the Equifax data breach (2017) lead to a loss of four billion dollars in stock value. The direct cost totaled an additional $49 million by the year-end. Such incidents have become common today.

Such incidents demonstrate how dependent financial firms are on third-party providers which may expose them further despite operational resilience improvements. Attacks also disrupt essential payment networks affecting economic activity like what was seen during the December breach at Lesotho’s Central Bank stalling national payments by domestic banks completely. To cope with these threats effectively, we need robust cybersecurity policies enforced through regulation, especially targeting interconnected systems, including those involving external vendors.

Types of Cybersecurity Attacks and How to Defend Against Them

Let’s take a look at some of the most common types of cyber attacks and learn how to defend against them.

1. Cross-Site Scripting (XSS) Attacks

XSS attacks involve injecting malicious scripts into web pages viewed by other users. The attacker’s script executes in the context of the victim’s browser, potentially stealing data or performing actions on behalf of the user.

How to defend Cross-Site Scripting

Ensure that all user inputs are properly sanitized and validated to prevent malicious code execution.
Implement CSP headers to restrict the sources of executable scripts on your site.
Encode data before displaying it on web pages to prevent script execution.

2. Whale-Phishing Attacks

Whale-phishing (or whaling) attacks target high-profile individuals, such as executives, with highly personalized and convincing phishing emails designed to extract sensitive information or commit fraud.

How to defend Whale-phishing attacks

Provide targeted training on recognizing phishing attempts and safe email practices.
Use advanced email security solutions to detect and block phishing emails.
Implement multi-factor authentication (MFA) and verify sensitive requests through separate communication channels.

3. DNS Spoofing

Also called DNS cache poisoning, DNS spoofing involves corrupting the DNS cache with false information. Users are redirecting to malicious sites or traffic is intercepted with DNS Spoofing.

How to defend DNS Spoofing

Implement Domain Name System Security Extensions (DNSSEC) to ensure the authenticity of DNS responses.
Set appropriate DNS caching policies and regularly clear caches. Clearing the caches will reduce the impact of spoofed data.
Implement DNS monitoring and intrusion detection systems to detect suspicious activities.

4. Malware

The term “Malware “ is a short form for “Malicious software.” Cybercriminals design such software to infect and exploit systems. Malware encompasses viruses, worms, trojans, and ransomware, or harmful codes that can steal data, damage or destroy files, or invade privacy. These software are designed to harm or exploit systems, including viruses, worms, trojans, and ransomware. Check if your computer is getting slower or showing unwanted pop-ups, these are the earlier signs of malware infection.

How to defend Malware

Use reputable antivirus and anti-malware programs and keep them up-to-date.
Regularly update your operating system and applications to patch vulnerabilities.
Avoid downloading software or opening email attachments from unknown or untrusted sources.

5. Spear-Phishing Attacks

Spear-phishing attacks are targeted phishing attempts aimed at specific individuals or organizations, often using personal information to make the attack more convincing.

How to defend Spear-Phishing Attacks

Conduct regular training on identifying and responding to spear-phishing attempts.
Encourage verification of unexpected or unusual requests through separate communication channels.
Implement advanced email filtering and threat detection systems.

6. Botnets

Botnets are networks of compromised computers controlled by an attacker, often used to perform distributed attacks such as DDoS or to distribute spam and malware.

How to defend Botnets

Use anti-botnet solutions and network monitoring tools to detect and mitigate botnet activities.
Keep operating systems and applications up-to-date to reduce vulnerabilities that could be exploited by botnets.
Use firewalls and intrusion detection/prevention systems to identify and block botnet traffic.

7. SQL Injection Attacks

SQL injection attacks involve inserting malicious SQL queries into input fields to manipulate or access a database in unauthorized ways.

How to defend against SQL Injection Attacks

Implement prepared statements with parameterized queries to prevent SQL injection.
Validate and sanitize all user inputs to remove potentially harmful SQL code.
Apply the principle of least privilege by restricting database access and permissions.

8. Watering Hole Attack

A watering hole attack involves compromising a website frequently visited by the target to infect their systems with malware.

How to defend Watering Hole Attacks

Regularly check and secure the websites your organization interacts with.
Implement web filtering and security solutions to block access to compromised or suspicious sites.
Train users to be cautious about visiting unknown or potentially insecure websites.

9. DNS Tunneling

DNS tunneling uses DNS queries and responses to exfiltrate data or communicate with a compromised server, bypassing traditional security controls.

How to defend against DNS Tunneling

Analyze DNS traffic patterns to detect unusual or suspicious activities.
Use DNS security tools to block unauthorized DNS tunneling activities.
Limit DNS queries to only trusted servers and configure network devices to inspect DNS traffic.

10. Distributed Denial-of-Service (DDoS) Attacks

DDoS attacks overwhelm a target's resources with a flood of traffic, causing service outages or disruptions.

How to defend DDoS Attacks

Use specialized DDoS protection services to absorb and mitigate attack traffic.
Use scalable cloud services or content delivery networks (CDNs) to handle traffic surges.
Apply rate limiting and traffic shaping to manage and filter incoming requests.

Who do cyberattackers target?

Cyberattackers target a wide range of victims based on different motivations and goals. Primarily, they look for vulnerable systems to exploit weaknesses. Individuals are often targeted through phishing attacks.

These attacks attempt to steal personal information like credit card details or login credentials by masquerading as trustworthy entities in emails or messages. Small to medium-sized businesses (SMBs) frequently face attacks due to weaker cybersecurity measures compared to larger corporations. SMBs can be the entry point for more extensive network breaches involving bigger partners or clients connected within their supply chain.

Large organizations attract cybercriminals seeking financial gain, intellectual property theft, and data breaches that provide valuable trade secrets or customer databases loaded with sensitive personal information. This includes banks where the aim is immediate money transactions unauthorizedly conducted through compromised systems inside the banking infrastructure itself. Hence, its pivotal role draws interest from black hat hackers looking for lucrative opportunities, making it clear why such prime targets are inherently drawn toward these hot spots.

How to protect yourself against cyberattacks

Protection against cyber attacks is a disciplinary trait. People need to follow certain best practices to minimize a potential cyber attack threat. These include:

Get Educated: Get educated with cyber security basics such as checking links and email addresses before clicking one or downloading an attachment. If you are running a business, train your staff with emphasis on the importance of verifying unusual requests through phone calls to reduce social engineering risks.
Use Encryption Technologies: Individuals should use encrypted applications while employers should encrypt both the customer and employee information. This will prevent unauthorized access during the breaches.
Backup Your Data: Having backups can save you from complete loss if ransomware hits. Make sure you automate the backup process to get the most recent versions of your data.
Keep Your Systems Updated: Software updates are modifications or additions to existing software programs that improve functionality, fix bugs, enhance security, or provide new features. Updating your system is essential for maintaining the performance and security of software applications and operating systems.
Ensure Secure Logins: Enable 2-factor authentication. Any login attempt from a system other than the regular one would initiate authentication with an additional 2-factor layer.
Restrict Admin Rights: Restriction of admin rights is another critical layer of defense. Only allow authorized personnel administrative privileges needed for their task while keeping others at minimal necessary permission levels.
Use Genuine Firewalls: Installing firewalls will help block brute force attacks automatically stopping malicious traffic intrusion immediately upon detection, making it a highly effective preventive measure overall!

What are Active and Passive attacks in Information Security?

Active and passive attacks are two broad categories used to describe the different ways attackers can exploit a system. Let’s understand each one by one.:

Active attacks involve some form of alteration or disruption of data or systems. An active attacker aims to alter or damage the system by unauthorized actions like modifying data packets. Attackers can trigger DoS attacks by overwhelming a network with fake data. For example, Active attackers may manipulate “Allow John” to “Allow Smith” to access a file. This compromises the integrity of your data. There is also a modification where attackers spoof messages which is another form of an active attack that disrupts normal operation. A different type called repudiation involves denying previous actions such as transactions or communications, making it difficult for systems to track who did what.

Passive attacks, on the other hand, involve monitoring or eavesdropping on data transmissions without altering or disrupting the data or systems. The attacker seeks to gather information discreetly without making their presence known or affecting system operations. These attacks are often harder to detect because they do not disrupt normal operations.

Examples of Active Attacks:

Man-in-the-Middle (MitM) Attack
Denial of Service (DoS) Attack
SQL Injection
Ransomware

Examples of Passive Attacks:

Eavesdropping (Sniffing)
Traffic Analysis
Footprinting
Network Scanning

What to do during a cyber attack

There can be different types of cyber attacks, and the impact of the attack can be punishing. As such, maintaining a calm approach can help you act swiftly and make the right decisions. Start with disconnecting your device from the internet. This will prevent further data loss or malicious activity spread.

If you working in an organization, notify your IT department right away. A fast response can help contain the breaches more effectively. If it’s a personal device, contact cybersecurity professionals for guidance. Then identify and isolate the affected system but keep powered on as it may hold critical forensic evidence that experts may need later.

Don’t turn off the infected device abruptly because this might destroy vital logs and indicators used during the investigation phases. Document everythingg about the attack. Record times of unusual activities like computer slowed downs or strange pop-ups.
