In this article, we explore some of the dangerous things that organizations are exposed to when a computer system is used and how they can affect businesses and individuals. It includes basic concepts, useful practices, and methods for securing information technology assets against various security threats.
What is Computer Security?
Computer security protects computer systems, networks, and data from unwanted access, theft, destruction, or disruption. It addresses security measures and methods that assure the property of digital data is not improperly used, secured, and accessible at any time.
Computer security is focused on what hardware, software, and data are stored inside a computer to guard from outside attackers or inside manipulators. It performs a regular security update to secure it against possible attacks by using access control, encryption firewalls, and antivirus software.
Common threats to computer security:
- Malware: Any software that is specifically designed to damage or exploit a system, including viruses, worms, or trojans.
- Phishing attacks: Phony emails or websites pretending to be trustworthy in an attempt to steal sensitive information.
- Denial of Service (DoS) attacks: Attempts to crash a machine or network by flooding it with traffic, making it unreachable for legitimate users.
- Man-in-the-middle attacks: Intercepting the communications between two parties in order to listen to or change it.
- Zero-day Exploits: Attacks using undisclosed vulnerabilities on software that are yet to receive any patches from the developer.
What are Computer Security Risks?
Computer security risk is any threat or vulnerability that can compromise the protection of the computer system, network, or other such data in an organization. This can lead to things like unauthorized access, data leaks, system crashes, and various other negative consequences.
Security threats can originate from a complex mix of factors that include cybercriminal activities, software vulnerabilities, human actions, and legacy systems. Identifying and understanding these risks will develop security efforts to protect digital assets from future attacks or breaches.
How do Computer Security Risks Affect Businesses?
Computer security risks can have significant impacts on businesses:
- Financial losses: The security breach could result in direct monetary loss, theft, fraud, or ransom payments.
- Data breaches: Customer data and intellectual property can be compromised by unauthorized access to sensitive information.
- Operational disruptions: Cyberattacks may lead to system halting, resulting in business interruptions and decreasing productivity.
- Reputation damage: Customers may lose confidence in a company and its services, leading to harming the company’s market name due to security incidents.
- Legal consequences: Businesses can receive legal sanctions and monetary fines when sensitive data protection is not done at an adequate level.
8 Computer Security Risks
Computer security risks continue to evolve and pose significant threats to individuals and organizations. Here is a list of the 8 most important computer security risks and the areas organizations should be paying attention to.
#1. Malware
Malware, or malicious software, has become a regular part of an organization’s computer security. Malware encloses viruses, worms, trojans, and ransomware. Malware may gain entry into an organization’s systems through methods like email attachments, browsing infected websites, or downloading compromised software.
As soon as malware enters a system, it may extract any sensitive information from the computer, corrupt files, or take hold of the device itself. Ransomware is a type of malicious software that gets itself into the target network, encrypts files, and holds data hostage until payment has been completed. Malware can briefly slow down the system and completely damage an organization’s data, as well as possible financial loss.
#2. Phishing Attacks
Phishing is another type of attack done by an attacker through the deception of tricking employees into disclosing sensitive information or carrying out harmful actions. Such attacks are usually in the form of emails, text messages, or a legitimate-looking website that extracts credentials or financial data.
Phishers act as legitimate entities that employees trust, such as banks, social media activity stream rates, or government agencies. Specifically, advanced phishing techniques known as spear phishing target specific individuals or organizations with highly personalized messages. Phishing attacks rely on social engineering and the human tendency to trust to become effective.
#3. Password Related Vulnerabilities
Poor and leaked passwords are a risk to security. Despite being aware of this, most employees of an organization still prefer to set low-security passwords or use a single password on all accounts. Weaknesses in passwords could enable unauthorized access to sensitive systems and data. Weak passwords can be exploited in a number of ways by attackers, such as brute-force attacks, dictionary attacks, and credential stuffing, to name just a few. This risk is increased even further if employees do not change default passwords on company devices or fail to enable MFA.
#4. Unpatched Software Vulnerabilities
Software vulnerabilities are the weaknesses of applications or operating systems which can be exploited by attackers. Usually, these vulnerabilities occur due to coding/design errors. When software developers find these vulnerabilities, they make patches or update the software to fix them. Despite this, many organizations do not install updates in a timely manner, and their systems are unprotected.
Exploited vulnerabilities can give rise to malware and other attacks, enabling the compromise of entire networks. Updating system software regularly and managing the patches are important for keeping it safe.
#5. Insider Threats
An insider threat originates from people inside the organization with legitimate access to systems and data. The nature of these threats can be deliberate (e.g., a disgruntled employee stealing data) or undeliberate (e.g., employees clicking on phishing scams or mismanaging sensitive information). Insider threats are especially malicious since they evade a lot of the protections against external attacks.
This is potentially harmful because it may lead to data breaches, stealing of intellectual property as well as sabotage of critical systems. It involves a mix of technical controls, employee training, and monitoring systems to identify a potential insider threat and mitigate it.
#6. Distributed Denial of Service (DDoS) Attacks
The goal of a DDoS attack is to make it difficult or impossible for legitimate users to access an application, service, or site by overwhelming the target system or network with traffic. The attacks can be directed against websites, online services, or entire network infrastructures. DDoS attacks have become larger and more sophisticated, capable of transforming vast amounts of traffic from an array of sources. A successful DDoS attack can cause service disruptions, damage to the company’s reputation, and financial losses.
#7. Man-in-the-Middle (MitM) Attacks
A MitM attack is when an attacker gets in between two parties and listens to or modifies information being sent. These take place over unsecured Wi-Fi networks, through compromised routers, or via physical malware on the employee’s device. A MitM attack often ends up with data stealing, credential harvesting, or injecting malicious content between seemingly legitimate communications. To mitigate MitM attacks, encryption protocols can be used by organizations along with strong communication channels and verifying digital certificate authenticity.
#8. SQL Injection Attacks
SQL injection is a type of attack that takes advantage of vulnerabilities in web apps where the code interacts with databases. Attackers insert malicious SQL code into application queries to gain access to the organization’s database. Such an attack can result in data theft, content being manipulated from the database, or even taking over the complete control of the respective server hosting a database.
SQL injection attacks take advantage of inadequate input validation and are also one of the most serious threats to any organization that stores sensitive data in its database. Secure coding practices, input sanitization, and the use of parameterized queries are essential to prevent these attacks.
Best Practices to Prevent Computer Security Risks
Computer Security is essential to secure computer systems and data from any threat. Here are five tips organizations can incorporate into their operations to avoid computer security risks:
1. Regular Software Updates and Patch Management
Keeping software updated is basic security hygiene. Because software updates are a common way to release security fixes for known issues, a systematic process should be used to update all software and firmware regularly. Computers such as desktops, servers, mobile devices, and network equipment, when possible, leverage automated update tools to ensure that patches are applied as soon as they become available.
Organizations should implement a patch management solution for testing and distributing updates. Keeping up with updates helps organizations stay protected against common exploits and can even fill in security gaps.
2. Strong Authentication and Access Control
Organizations should use strong authentication to avoid unauthorized access. They should make sure that all accounts are protected by strong, unique passwords. Passwords must be made up of uppercase and lowercase letters, together with numbers and special symbols. Securing MFA wherever possible should add additional layers of security to the passwords.
When available, organizations should use biometric verifications. Role-based access control (RBAC) should be implemented throughout the organizational system to ensure that users are only accessing the resources needed for their job functions. Access permissions should be reviewed and updated regularly, particularly when employees change roles or leave the organization.
3. Comprehensive Security Awareness Training
Organizations still face many security breaches due to human errors. To prevent this, organizations should conduct periodic security awareness training for all employees. This should include information on how to recognize phishing attacks, how to browse securely, how to manage sensitive data, and the necessity of complying with security policies. Educate employees on generating strong passwords and password management.
Test their knowledge using simulated phishing attacks, prompting them to remember what they have learned. Make sure to remain relevant in the domain of threat trends and incidents with the training material. Encourage a security awareness culture where employees feel responsible and involved in protecting organizational assets.
4. Network Security Measures
Organizations should install and manage firewalls to filter in-and-outbound traffic. Intrusion detection and prevention systems (IDS/IPS) are other tools to detect and even avoid attacks. Segment networks to confine important frameworks and restrict the spread of potential interruptions. Protect sensitive data during transmission as well as when stored. Deploy secure remote access solutions through the use of virtual private networks (VPNs). Performing regular network scans and vulnerability assessments to discover weaknesses.
5. Regular Backups and Disaster Recovery Planning
A strong backup strategy will help organizations defend against data loss due to security incidents, hardware failures, or disasters. Frequent data, system, and configuration backups for resilience against any disaster. Backup data to a safe, out-of-site location or organizations can use cloud-based backup services. The backup data must be encrypted to prevent unauthorized access. Backups should be tested ahead of time so that they are assuredly verified to be restored successfully.
Organizations should plan for all natural disasters through a detailed and thorough systems outage or failure plan that serves as documentation within the security incident detection and response management process. Keep the DR plan updated and test it out on a periodic basis to check its ability to mitigate the processes in real life.
Mitigating Computer Security Risks with SentinelOne
SentinelOne provides security solutions to mitigate computer security risk, using artificial intelligence and machine learning technologies to defend organizations against a wide range of attack vectors. Let us see how SentinelOne addresses these security challenges:
Endpoint Protection Platform (EPP)
SentinelOne EPP uses AI-driven technology to detect and prevent a broad spectrum of threats in real time. It watches for suspicious activity and monitors system behaviors and file activities that are indicative of malware, exploits, or other malicious actions.
Unlike signature-based detection, which is limited to identified threats, it detects not only known but also unknown threats, such as zero-days, by recognizing patterns and behaviors. This allows it to either respond automatically to the evolving threats that may surpass traditional antivirus solutions or block them entirely.
Automated Threat Response
Automatically responding to threats detected is another key feature of SentinelOne. It acts fast by isolating affected endpoints, killing malicious processes, and preventing the spread of threats across the organization’s network when a security risk is identified. This ability to respond automatically minimizes the impact of security incidents and lessens the burden on security teams.
Endpoint Detection and Response (EDR)
With powerful EDR capabilities, SentinelOne offers deep visibility into endpoint activities so that security teams can investigate and respond to threats. Such a platform collects and analyzes exhaustive telemetry data from endpoints, which helps an analyst perform extensive forensics on any security incidents. This also helps organizations understand the overall extent of an attack, along with where it originated and what steps need to be taken for remediation.
Network Traffic Analysis
This is where SentinelOne goes beyond endpoint protection by monitoring network traffic to identify threats that fall out of scope for individual devices. With this visibility across the network, it can identify lateral movement attempts and data exfiltration as well as other types of attacks. Combining network activity with endpoint would give SentinelOne better overall visibility of the security landscape, all for better threat detection and response.
Cloud Workload Protection
As organizations migrate their infrastructure to public clouds, SentinelOne also protects workloads and containers in the cloud. With this feature, security policies are applied over VMs, containers, and serverless infra regardless of the underlying computing layer, thus creating consistent protection for hybrid and multi-cloud deployments. It enables organizations to maintain compliance and protect against other threats specific to the cloud.
Conclusion
With everything going digital, computer security risks are getting more and more diverse. Keeping digital assets and information safe, however, requires caution. A layered security strategy is critical to minimizing an organization’s risk.
Some of the steps include making sure best practices are in place, such as software updates, authentication methods, security awareness training, network security solutions, and backups. Organizations can also take advantage of AI-driven detection and highly capable automated response within threat-agnostic protection solutions like SentinelOne, which help make organizations incredibly resilient against various adversaries, as well as throughout the attack surface, such as endpoints and networks.
