Amidst the global love for all things mobile—smartphones and tablets, the good old computers (desktops and laptops) still hold a strong ground. The wider screens, higher storage capacity, and new-gen processor speeds—who doesn’t love all these features? But are desktops and laptops less prone to unauthorized access? Indeed their bigger size is a decisive factor in the lower lost or stolen probabilities of these computer devices than their mobile counterparts. Yet, individuals and businesses need to know how to prevent unauthorized computer access.
In this blog, we learn about unauthorized computer access, the possible causes, and how businesses can leverage a Unified Endpoint Management (UEM) solution to prevent unauthorized access to computer systems used for work.
What is Unauthorized Access ?
Unauthorized access to data occurs when individuals gain entry to an organization’s systems, networks, or data without permission. Cybercriminals often use this tactic to gain access to data, deploy malicious software, and take advantage of security vulnerabilities. Such breaches can have serious consequences for both the business and its customers.
This unauthorized access can take various forms and is typically associated with malicious intent, ranging from cybercrime activities to espionage, data theft, or other illicit actions.
For businesses, it’s more important than individuals to know how the risk of unauthorized access to computers can be reduced. The reason is simple. The data-related consequences of unauthorized access to work computers can be far more insidious than those of personal computers.
Risks and impact of unauthorized access
Unauthorized access to data poses serious risks, making it crucial to implement immediate protective measures. Individuals who attempt to gain access without permission often have one of the following goals:
- Disrupt Electronic Systems: Some hackers aim to cause disruptions or play pranks. By accessing sensitive data without permission, they can force a company or organization into a state of high alert, potentially leading to a shutdown of systems.
- Harm the Target: Unauthorized access to sensitive information can lead to significant damage for the victim, such as triggering a data breach. This can result in legal issues, loss of trust, and a damaged reputation.
- Steal Data: Data theft is one of the most common motives for unauthorized access. Stolen data can be used to extort individuals, businesses, or organizations. Often, exposed and stolen credentials are the first targets in a data breach.
- Cause Physical Damage: If unauthorized access is gained to certain systems, hackers can cause physical damage to devices connected to the network, leading to costly repairs or replacements.
By understanding these risks of unauthorized access, organizations can better prepare to protect their systems and sensitive data from unauthorized access.
Possible Causes of Unauthorized Access
Unauthorized computer access can occur due to various factors, often stemming from vulnerabilities in security practices, technology, or human behavior. Understanding the possible causes is essential for implementing effective measures to prevent and mitigate such incidents.
Here are some common causes of unauthorized computer access:
Weak Passwords
- Use of easily guessable passwords, such as “password” or “123456.”
- The lack of password complexity and diversity makes it easier for attackers to crack or guess passwords.
Stolen Credentials
- Phishing attacks targeting users to obtain their login credentials.
- Credential harvesting through malware, keyloggers, or other malicious software.
Insufficient Authentication Measures
- The absence of multi-factor authentication (MFA) allows unauthorized users to gain access even with compromised passwords.
- Weak or easily bypassed authentication processes.
Unpatched Software and Systems
- Failure to apply security patches and updates promptly leaves systems vulnerable to known exploits.
- Outdated software with unaddressed security vulnerabilities.
Inadequate Access Controls
- Improperly configured access controls, granting unauthorized users or entities excessive privilege
- Lack of role-based access controls, allows individuals to gain unauthorized computer access compromising the data or systems.
Social Engineering Attacks
- Manipulation of individuals through deceptive means to divulge sensitive information or perform actions that compromise security.
- Exploitation of trust to gain unauthorized access.
Malicious Insider Threats
- Employees or individuals with authorized access exploit their privileges for malicious purposes.
- Disgruntled employees seek to harm the organization by accessing and manipulating sensitive data.
Insecure Network Connections
- Unprotected Wi-Fi networks are susceptible to eavesdropping or unauthorized access.
- Insufficient network security measures allow attackers to intercept data.
Software Vulnerabilities
- Exploitation of software vulnerabilities to gain unauthorized access.
- Use of malware or exploits targeting specific software weaknesses.
Inadequate Monitoring and Detection
- Lack of robust monitoring systems to detect unusual or suspicious activities.
- Failure to respond promptly to security alerts or anomalies.
Ways to Prevent Unauthorized Computer Access Using UEM
Preventing unauthorized access to work computers is crucial for businesses. The lack of prevention against unauthorized access can lead to data breaches, regulatory penalties, and damage to a brand’s reputation.
To effectively address this risk, implementing a robust Unified Endpoint Management (UEM) solution is key. This guide outlines essential UEM features that help prevent unauthorized access to work computers.
UEM capabilities can be applied across multiple work computers from a centralized console. After enrolling devices, businesses can categorize them into device or user groups. Once set up, policies to prevent unauthorized access can be enforced across an entire fleet of work computers, typically including Windows and macOS systems.
Passcode Policies
A. Complexity Requirements
- Enforce stringent passcode complexity rules to deter easily guessable passwords.
- Require a minimum length, alphanumeric characters, and a combination of uppercase and lowercase letters.
B. Expiry and Change Policies
- Implement periodic passcode expirations to enhance security.
- Enforce an AUP necessitating users to change their passcodes at regular intervals.
C. Failed Attempts Lockout
- Configure a mechanism that temporarily locks out users after a specified number of consecutive failed passcode attempts.
- Define a duration for the lockout period to discourage brute-force attacks.
Patch Management
A. Regular Updates
- Establish a systematic approach to ensure timely installation of operating system and software updates.
- Automate patch deployment processes to minimize the window of vulnerability.
B. Vulnerability Assessment
- Conduct regular vulnerability assessments to identify and prioritize security flaws.
- Develop a protocol for swift patching of identified vulnerabilities based on their criticality.
Web Content Filtering
A. URL Whitelisting and Blacklisting
- Implement URL or website whitelisting to permit access only to approved websites.
- Employ URL blacklisting to block access to known malicious or inappropriate sites proactively.
B. Category-Based Filtering
- Categorize websites based on content, allowing administrators to define access policies accordingly.
- Restrict access to specific categories that may pose security threats or violate organizational policies.
Device Encryption
A. Full Disk Encryption
- Mandate the use of full disk encryption to safeguard data stored on endpoint devices.
- Implement encryption algorithms compliant with established standards to ensure data confidentiality.
B. Removable Media Encryption
- Extend data encryption measures to removable media to prevent unauthorized data extraction.
- Enforce policies requiring the use of encrypted USB drives for data transfer.
Multi-Factor Authentication (MFA)
A. Authentication Layers
- Integrate MFA to add an additional layer of security beyond traditional username and password authentication.
- Utilize diverse authentication factors, such as conditional login, to enhance access control.
