What is The Best Security System for Your Computer

Updated: Jan 19

In today's technologically advanced world, safeguarding the integrity and confidentiality of your computer security has become more crucial than ever before. With the increasing prevalence of malware and cyber-attacks that target sensitive information, it is imperative to take proactive measures to ensure the safety and security of your digital devices.  

It is essential to ensure the safety and security of your computer and its contents, regardless of whether you use it for work, personal use, or both. You need to consider a wide range of threats when it comes to computer security, such as malicious hacker attacks and theft of your device and confidential data. 

Importance of Computer Security 

Cybercrime is on the rise

600,000 Facebook accounts are hacked daily, and one in three US homes has a computer infected with malware, according to the CISA.  Adhering to appropriate security protocols could have prevented numerous security breaches. 

Computer security guards against cyberattacks and the loss of critical data for people and businesses. Becoming the target of a cybercriminal can have severe consequences, causing significant harm and disruption to one's daily activities, both personally and professionally. 

Key Cyber Security Threats 

Best Security System

Hackers find most home and business computer systems to be attractive targets. Data theft is getting unauthorized access to private, secure data assets to steal the data or to continue having access to databases for corporate espionage. 


Denial of service (DoS) attacks try to bring down a system or network by overloading it with traffic, making it impossible for the intended users to use it. Distributed denial of service (DDoS) assaults are another common cybersecurity threat when multiple computers coordinate attacks against a single target.  


Trojans are malicious programs or codes that masquerade as trustworthy and can be found in email attachments, games, and apps. After downloading the trojan, an unwary victim permits it to take over their device. 


Malware, short for malicious software, is a category of computer programs designed to disrupt a system's functioning to obtain access to, commandeer, pilfer, or cause damage to digital assets. This cyber threat includes ransomware, worms, trojan horses, and other harmful software. To keep systems safe from these computer threats, computer security experts must maintain constant watchfulness and adapt when new malware strains pose unknown risks to computer security. 


Since no computer system is flawless, many software programs have backdoors—unintentional flaws that allow malicious actors to enter a system without following standard security protocols. Backdoors are a cybersecurity risk that needs to be addressed. They may be introduced for valid purposes or subpar development or setup procedures.  


A malicious actor can obtain credit card information and passwords from an unsuspecting victim using spyware. Spyware can affect desktop applications, desktop browsers, and mobile devices. 

Laptop Security Essentials  

Because laptops are more prone to physical theft or loss than desktop computers, you should take extra security measures if you use one.  

These are the essential security practices that you need to follow: 

Physical Security Measures

Never leave your laptop alone in public areas; always lock it when not in use. You should also use a cable lock or a laptop safe to secure your laptop to a stationary item or a safe place. If your laptop is lost or stolen, you should also register it with the manufacturer or tracking service and label it with your name and contact details. 

Best Practices for Password Protection 

You should always use a strong password that you routinely change while logging into your laptop. You should never share your passwords with anyone and use unique ones for all your accounts and services. Additionally, you ought to use a password manager to safely store and manage your credentials and activate screen locks and sleep modes that require a password to exit. 

Biometric Authentication 

Since biometric techniques are more convenient and safer than passwords, you should also consider utilizing them to unlock your laptop. Examples of these techniques include fingerprint, face, or iris recognition. If the biometric system malfunctions or is compromised, you should also have a backup password. 

Essential Security Components 

Besides laptop security essentials, install and update these crucial computer security components:  

  • Endpoint Security 

  • Network Security 

  • Data Protection through Encryption 

These components guard against cyber threats, unauthorized access, intrusion, or attack and protect your data from unauthorized access. Use other security solutions to improve your computer security per your needs and preferences. 

Endpoint Security 

Endpoint security prevents dangerous threats and cyberattacks from harming workstations, servers, and other devices (that can accept a security client). By putting endpoint security software in place, businesses can defend employees' work devices or servers in the cloud or on a network from internet threats. 

Choosing The Right Endpoint Security Solutions  

Endpoint security typically includes antivirus software, firewall, and other features that detect and prevent malicious activities on your computer. Here are some tips on choosing the right endpoint security solutions for your computer

Detection and Response

Every danger that enters the network must be able to be identified by an endpoint protection suite, including cyber threat detection. Naturally, the majority of malware is made to avoid detection. The issue with this is that unless your system starts acting strangely or slows down, you can only sometimes tell if something has gotten past defenses. Because of this, it's critical to analyze your network traffic routinely.

Don’t Miss Your Key Points as You Select Your Security Partner  

Monitoring and Recording

Managing all your endpoints is the primary goal of your endpoint security solution. This entails keeping an eye on and documenting network activity around the clock. Because of this, ensure the endpoint security solution you choose includes effective monitoring features. 

Automation Capabilities

In response to security risks, how does endpoint security act? Is there an automated method in place to handle false positives? Because when it comes to network security, there will be a lot of false alarms. There's just no avoiding them. However, automated features might assist you in effectively addressing problems. 

What precautions should be taken to make a computer more secure? 

To improve the security of your computer, follow these steps: Avoid opening emails from unknown senders, back up your data regularly, regularly check your firewall to ensure it is active, avoid visiting suspicious websites, be cautious of deals that seem too good to be true, and never share sensitive information online. 

What are Network Security Measures 

Network security measures are controls to ensure network availability, confidentiality, and integrity. Even though a lot of fundamental data is readily available, these controls are constantly changing. It takes a massive effort to keep hackers out of your network. Firewalls, proxies, and gateways all help achieve that objective. 

It is risky to assume your network is protected from hackers because you have these devices. Eventually, hackers succeed in gaining entry. Prolific hacker Kevin Mitnick claims to have successfully tested the network security of companies he has been hired to evaluate with 100% success

Data Protection through Encryption

Information can only be accessed by those with a password or secret key, also known as a decryption key, thanks to data encryption, which changes the format or code of the data. Unencrypted data is called plaintext, and encrypted data is called ciphertext. Companies often use encryption to secure their data. There are two main types of encryption: symmetric and asymmetric (public-key) encryption. 

Symmetric Encryption vs Asymmetric Encryption

Symmetric encryption is faster and more appropriate for closed systems because it only requires one private key for encryption and decryption. Nevertheless, it might be preferable for open systems because key sharing can result in theft. The most used kind of symmetric encryption is AES. Public and private keys used in asymmetric encryption are theoretically related. Since no risk is involved in sharing the public key, it is perfect for public networks like the Internet. The asymmetric encryption types that are most used are RSA, DSA, PKCS, and ElGamal. 

Common Encryption Algorithms 

Triple DES

Triple DES is a symmetric encryption method that uses three 56-bit keys, totaling 168 bits. It was designed to replace the Data Encryption Standard algorithm, which was vulnerable to hacking. Though it was once widely used, it has mostly been replaced by the Advanced Encryption Standard. 


The US Government and other institutions employ the reliable encryption method AES. It can be used with 192- and 256-bit keys for solid encryption and is very effective in 128-bit form. Except for brute force assaults, which attempt every conceivable combination to decode the messages, AES is thought to resist all attacks. 

RSA Security

RSA is a public-key encryption algorithm that encrypts internet data in PGP and GPG programs. It's asymmetric and uses two keys - public for encryption and private for decryption. 


Blowfish is a fast and effective algorithm that encrypts messages in 64-bit blocks. It's widely used in software categories like eCommerce and password management due to its flexibility and availability in the public domain. 


A computer security expert, Bruce Schneir, created Blowfish and its successor Twofish. Twofish is a fast, symmetric algorithm ideal for both hardware and software environments. Like Blowfish, it's free to use. 

File Encryption vs. Full Disk Encryption 

Full-disk encryption is the process of encrypting an entire disk drive, where a single encryption key is used to encrypt all data on the disk. On the other hand, file-based or file-level encryption encrypts a single file or a small group of related files on a disk. Unlike full-disk encryption, file-based encryption uses unique keys to encrypt each file on a disk or drive. 

Combatting Malware Threats 

Cybercriminals utilize malware, or malicious software, to take advantage of, harm, or interfere with a network or endpoint. Malware can extort money, take over a system, encrypt data, spam users, spy on users, steal or destroy data, and alter system functionality. 

Types of Malwares

Malware can take many forms, including viruses, worms, ransomware, spyware, adware, trojans, and rogueware. These threats can infect devices, encrypt data, steal information, compromise security, and more. 

How to Prevent Malware Attacks 

To prevent malware from propagating throughout an organization, cybersecurity professionals should implement security software, multi-factor authentication, strong password restrictions, employee education, and micro-segmentation technologies. They should also keep IT systems and software up to date, remove unnecessary programs, and mandate the use of secure email clients and web browsing. Malware prevention is a full-court press, with multiple components collaborating to enhance defense.  

7 Practical Ways to Enhance Computer Security  

Recent estimates indicate that over $3.6 billion in reported losses in the UK are attributable to cybercrime, which is expected to continue climbing. At Prismware, we offer a few easy suggestions for malware prevention and enhanced cybersecurity. 

Strong Passwords

Weak passwords are among the most frequent reasons for cybersecurity breaches, as users frequently reuse them across several or all accounts. According to a Specops Software poll, 51.61% of participants share the passwords to streaming websites they use, with 21.43% of participants not aware if such passwords are then shared with third parties. 

Two-Factor Authentication

Multi-factor authentication requires at least one additional form of personal verification to access software or complete a transaction. 

User Awareness and Education

It's essential to educate your users on common cyber threats, best practices for cybersecurity, significant trends, warning indicators to look out for, and how to report any suspicious activity. 

Enforce Safe Email and Browsing

To mitigate malware's damage, users should carefully review emails, scan for strange email addresses or text layouts, and avoid disclosing private information. Additionally, users should be cautious while browsing the internet, prevent websites without "HTTPS" in the URL, and refrain from connecting to public Wi-Fi networks. 

Regular Software Updates

Avoid non-company-wide, non-mobile-compatible features to enhance cyber threat detection. Regular patches and software upgrades secure against cyber-attacks and optimize system performance. 

Backup Strategies

Ensure proper organizational or technical safeguards are in place to protect personal information. Cyberattacks can be avoided and their effects reduced (e.g., by storing CVV codes apart from other card information). 

Monitoring and Auditing

Which weaknesses are hidden in your systems? Are you aware? If there's time to spare from "business as usual" chores, now could be an excellent moment to strengthen security, secure the parameters, and conduct penetration testing.

Final Words 

After reading this post, we hope you have a comprehensive understanding of computer security, common cyber security threats, and how to stop malware attacks. Cybercriminals who build malware have networks always brainstorming and experimenting with new attack techniques. Security experts must construct, manage, and update cyber defenses using a comprehensive strategy.
