Network Security – Protecting the Home Users, SMEs and Large Enterprises

Nowadays, the computer and the Internet play huge roles in running businesses, whether it is at-home, small, medium or large enterprises. The computer and the Internet is used in marketing and presenting the products, studying the market, interacting with clients and most of all conducting transactions with clients or business partners.

With the great importance of Internet and computer in running any business, clearly there is a huge importance of securing the network particularly those networks where sensitive and important data has been stored. In fact, it is very common in every news headlines, publications or televisions that computer networks from different companies have suffered security breaches and that lead to huge losses in their financial and social status in the business world.

This is why it is important to have a network security service that not only checks the vulnerabilities in the system but also protect those vulnerabilities from being exploited, much better if the services can prevent any attack from ever happening to the company. What do you think will happen when clients lost their important information when they were conducting business with you?

Yes, it is embarrassing but it is just the start. Since the system has been compromised you will have to pay huge amount of money just to fix the system, perform computer forensics, strengthen security and recover the stolen data. The company’s reputation will be damaged and it could lead to loss of investments and customers which could lead to the company’s downfall. So how can an at-home, small, medium or large enterprise protect their networks?

In fact, the answer should never be hard because there are many ways to protect and secure computer networks. Some attacks that threaten most business are when hackers steal the credit card or personal information of the clients of the business or exploiting their social security numbers. So in order to prevent this from ever happening companies and institutions must perform a regular security audit on their system. Large companies and institutions like hospitals and universities are required to accomplish this task. However, there are some businesses that do not have the enough resources to perform this task and these are small and medium enterprises making them the most vulnerable to these attacks.

Since hackers will employ different means for them to breach or gain access to the company’s system; companies must replicate all or at least most of those methods when auditing their security system. An audit on the system will check the vulnerabilities or weaknesses of the system’s structure; this is what every security expert and digital computer forensics professional call as penetration testing. Penetration testing is all about isolating each security threat, whether it is mild, moderate or critical; furthermore, it is used to determine the best set of actions against each threat.

In a pen test, the key areas of the system have to be targeted to completely enforce the company’s network security. It will help prevent any financial loss from frauds, hackers or extortionists or the lost of revenue because of unreliable business processes and systems. Not complying with the?recommendation could possibly lead to loss of important data, penalties, bad reputation from the media and the public sector and ultimately losing the business. For the employees, it could mean losing the job and if a certain employee is the source of the problem, he or she would face prosecution and possibly land behind bars.

When it comes to regular home user or at-home businesses, there are a few basic details one has to accomplish, particularly if they have a wireless network system in their home. There are easy and effective ways to protect the network from hackers and other users who want to piggyback on the system.

Add security by changing the SSID or the name of the network. Disable SSID broadcast and DHCP Control Mac Address Filtering. Add more security in your system by adding WEP encryption to block other mechanisms and means of the hackers. And further improve your security by setting a random 10 characters pre-shared key to ensure that the network is safe and secured; locked by a random mix of numbers and also letters. Together with effective firewall and anti-virus software, at-home businesses can strengthen the security of their system, no need for any computer forensic course or any other security training, but it won’t hurt to have them.

Computer Securities – The Threats to Computer Systems Part 1

Without a doubt, almost everyone rely on the computer and the internet just to complete their homework as well as work. Computers are also used to create and store important information and these informations have to be kept and stored in a secure and safe database. It is also important to us to protect our computer from abuse and misuse and also prevent any data loss in our computer’s operating system.

Computers used in companies and industries must have tough securities like firewalls and anti-virus and security methods like penetration testing so that vile minds cannot access the stored crucial information. Home users and other individuals must be cautious and perform any means necessary to protect their credit card information whenever they conduct any online transactions. If not then the computers they have will be at risk from any threats that could lead to the loss of important information, damage to the software, data and processing capabilities and cause damage to the hardware.

This intentional breach on the security and the system of a computer is called as the computer crime and this crime is under the same category as cybercrime. Cybercrime is one of the most known illegal acts nowadays and these acts are based on the Web; many security industries as well as law enforcement agencies in the world are facing this problem head-on. In fact, they have uncovered the different types of attackers in the cyber highway: the hacker, cracker, cyber extortionist, cyber terrorist, unethical employee, corporate spy and the script kiddie.

Hacker

In the past hackers were people known to have good skills with computers, but now the term hacker has a different view. Hackers are people who access any computer or any computer networks and systems without the permission of the network administrator. These people often claim that the reason why they access the system is to point-out the leaks and vulnerabilities of the system. Sometimes this reason is just a front for the hacker’s mischief.

Cracker

Cracker, even from the start was never associated with any good deeds in computer security. Cracker is just the same as the hacker, but most of the time, crackers will intentionally access any computer or any computer network for vile purposes like stealing important data or information or perhaps destroying the system, database or information on the system. Both the cracker and the hacker are extremely advanced when it comes to their skills.

Cyber Extortionist

Cyber extortionist is like a black mailer. This individual will use emails in an offensive way, sending threatening emails to the company or an individual. The mails will tell the company or that individual that these extortionists will release the important or confidential information, exploit the security vulnerabilities, or perhaps launch a cyber attack that will harm a person or a company’s network. They will ask for money in order to prevent the cyber threats from ever happening.

Cyber Terrorist

Cyber terrorist is a person who exploits the computer network or Internet in order to destroy the systems or computers for political purposes. It is comparable to a typical terrorist attack; these individuals are highly skilled specialists and their plot takes years of planning as well as substantial amount of money to implement their plot.

Unethical Employee

Unethical employee is a worker in the company who will illegally access the company’s network for several reasons. One reason could be to steal important secret data or information and sell them on the black market or perhaps a bitter employee who wants to exact revenge on the company.

Corporate Spy

Corporate spy is a person who has excellent skills in computers and networking; this person is hired to break into the specific network or computer of a company and steal or perhaps erase any important data or information. Some companies will hire these people to perform any corporate espionage missions. They are hired so that these companies will have leverage against their competitors.

Script Kiddie

Script kiddie is the same as a cracker; they have the same intention of doing dark deeds that could harm the computer, system, company or individual. However, the only difference is that the script kiddie lacks the technical know-how. In fact, these people are beginners or silly teenagers that will only use pre-written cracking and hacking programs.

Companies and also every individual must exert their best effort to safeguard their computers and systems from these types of person. Although, they may not know who they are but they can deter their plots by improving their networks security by performing pen test, which can be performed by a person who has completed penetration testing training.
