External attacks are attempted by individuals without any assistance from internal contractors or employees. These attacks are performed with the use of predefined technologies and plan. It involves the process of gathering and scanning information. You can also defend this attack by scrutinizing the logs of existing firewall. You can also install intrusion detection software to identify various external threats.External attacks are divided into sub categories including structure or unstructured attacks.

Structured external attacks:

These types of threats originate from a group of malicious people or organization. These types of network attacked are performed by such individuals who think premeditatedly on the actual losses and damages. There is need to implement access control procedures, detection system and hacking tools.

Unstructured external threats: These types of attacks are attempted by inexperienced attackers. A script kiddie is the type of terminology that is related to inexperienced attacker. They use cracking or scripted tools on the web to invade the system of target source.

Internal threats: Internal attacks are performed by unhappy or dissatisfied contractors or employees. These attackers have access to the system and try to steal information from normal process. These hackers have administration privileges on the network. You can easily block these types of attack through intrusion detection system that configure these attacks both from internal or external.

Point to remember:

There are some core components that you need to remember when you design network security infrastructure for your organization.

• Network attack detection.
• Network attack prevention.
• Network attack recovery
• Network attack isolation.

Identification of entry point

You should need proper scanning programs to trace all entry point of hackers into the internal network. You need to take assistance of skilled ethical hacker to identify these security points.

Penetration tests

If you run some type of penetration tests, it will help you to identify possible vulnerable points that can be easily accessed both internal and external users. It will help you to thwart attacks from multiple external sources.

Configure firewalls

You also need to install good antivirus software and some other security measures to protect your network from hacker’s attacks.

Data is the most valuable thing on the computer as people need first place precautions to save data from unexpected risks. Data is made up with the combination of bits and bytes and you need to put it on first priority when you apply protective strategies on it. Some sort of data is very confidential as firms apply different data protection techniques on it so that unauthorized user cannot access it. Exposure of credit card number, bank account information and social security number are the sensitive sort of data that has high level exposure of theft. Here, I would like to share some ways to protect data from unauthorized access and loss.

Back up Regularly:

The most important way for data protection is to take quick back up of it regularly. If you are using windows, you can use the window data backup utility to perform the process of back up. With the use of wizard mode, it is easy to create and restore back up. You can also configure the backup setting manually and there is need to set a schedule back up so that it can performed back up task automatically.  There are different back up programs that offer many options. It does not matter of what type of program you use, it is better to store a back up copy of this program in offsite. It saves your data in case of fire, natural disaster and tornado that can destroy your back up discs and tape.

Use share-level security

If you want to protect data from unauthorized access, it is important to set permissions on folders and files. If you are managing data in share network, you need to set share permissions so that user can access it in accordance to their rights and permissions. With the use of XP/windows 2000, you can perform it on the click of permission button on the tab of sharing in the properties of files and folders. However, you cannot apply these permissions on the local computer where data is stored. When you share computer with someone else, you need to share these permissions. These file level permissions are placed in the security tab of the properties sheet and it is more granular than common share level permission. In both situations, you can easily set permission on groups and accounts and allow various level of access from read only control.

Password-protect documents

Many applications like adobe reader and Microsoft allow users to set password on their important documents. You can set it easily by going to tools/options/ security tab. Some zipping software like WinZip can be used to encrypt and compress data.

Use EFS encryption

Server 2003, window 2000 and xp pro use encrypting file system to secure data. You can use encrypting folder or file option by clicking on advanced button existed in the general tab of the properties sheet. You must remind that you cannot use NTS compression and EFS encryption at the same time.

Disk encryption

There are many third part products that provide you the way to encrypt the whole disk. It locks down the contents of the hard drive that look transparent to user. In this way, data is encrypted when it is stored on hard drive and decrypted when it is loaded into media memory.

Public key infrastructure

Public key infrastructure is the way of handling private or public key pairs as these keys are issued by third party to implement security measure on data. You can easily protect data by the use public key encryption and other person will able to decrypt it if he or she holds the private key code.

Steganography

Steganography is the way to hide data into other data. For instance, you can easily hide a text into a message within mp3 music, text file and jpg graphic file. It uses encryption software to hide data and then decrypt it when data is reached at secure place. Steganography needs the exchange of secret key to perform this task successfully.

Secure wireless transmission

When you send data on wireless network, hackers can easily access it with the use of portable computer and wireless antenna. You need to store or send data on such wireless network that use encryption like Wi-Fi protected network access.

Rights management

Windows provide your RMS (right management service) to manage documents that you send to recipient as he can only read it but cannot modify or change and save it. These are some data protection techniques that help you to protect data in secure way.

A computer virus is the type of computer program that is hidden in other program to produce its copies in other locations of hard drive. It performs a malicious action like creation of clusters and data destruction. There are many types of viruses and worms that affect computers in various ways. However, common categories of computer viruses are worms and macro virus. Computer viruses are not naturally generated as they are man-made products. Once these viruses are created, they are released on internet as their spread is not under control of human.

Macro viruses: Micro virus is the sort of code that is usually embedded in the data files. Some spread sheet and word processors programs like Microsoft excel and Microsoft word permit you to attach macro with created documents. In this way, these documents customize and control the programs that create or extent the macro viruses program. For instance, a document attached with macro may execute whenever you save it and it can run external spell checking program to generate error in the text.

Stealth viruses: An active stealth virus makes modification in files or boot records and then hides them. It performs this task by monitoring the functions of the system that is used to read sectors and files from storage media. Sometimes the modification of stealth virus remains undetected for antivirus programs. If you want to eliminate it, the virus must be existed in memory at the execution of antivirus program.

Polymorphic viruses: It produces various operational copies in the system that is undetectable for virus scanners. One way of eliminating Polymorphic virus is performed through self-encryption with the use of variable key. Some sophisticated type of polymorphic virus can change the sequence of instructions. A simple virus scan program cannot identify and remove the infection of this virus. It requires sophisticated scan engine to search and eliminate it.

Boot sector viruses: Boot sector virus infects their own code in dos or master boot record of the computer. Master boot record is the small type of program that runs at the start up process of a computer. It monitors the boot sequence and decides about the computer partition from the boot. Boot sector virus is very dangerous as it infects hard drive easily. You need a bootable antivirus disk to remove boot sector virus from your computer.

Worms: Worms work like viruses that generate functional copies in computer through network connections. It infects the normal use of the pc and it is tough to remove them because they exist as separate items. Worms have too many similarities with viruses so they are also referred as viruses.

Trojan horses: The name of Trojan house is kept on the image of wooden horse founded in Greeks. Trojan horse virus is the type of program that affects the speed and performance of the computer. Some people regard it replicating malicious programs as it infects numerous harms to their computer. There are different types of Trojan viruses and there is always need of reliable antivirus program so that your computer can save from the infections of these viruses.

When you are connected to the internet, you are exposed to a number of hackers and intruders who can create much havoc in your computer system. If your computer system is hacked unluckily, then all your personal information is exposed to the hacker. This can be a severe problem. Moreover, your computer files and operating system can be corrupted and rendered useless. This means you have to re-install everything new into your computer which can take away much of your time and effort.

A computer virus or hacking techniques such as Trojans, key loggers, spyware, dialers and other malware can create a lot of problems for you. If there is an illegal or unauthorized intrusion into your system, then all your personal information in the computer will be access which could be your credit card number, your passwords, your bank account number or any other details .Here are a few suggestions that can help you being secure while you are connected to the internet.

To prevent all this from happening, firstly you should install a good anti-virus software. A good anti-virus software can be downloaded for free from any website. Different anti-virus software have different functions. Some software destroy the virus when if it enters the computer while others  prevent it from entering altogether. McAfee and Norton are one the most famous anti virus software and their ratings so far has been good. There are anti-adware and anti-spyware software as well which prevent any malware disrupting your computer.

A second factor that you should consider is firewall configuration in your computer. A firewall acts as a barrier in checking all the incoming and outgoing information to and from your computer or a network. Configuration of firewalls is done on the extent of security that is required. The firewall will filter the messages and the data according to IP address, ports, protocols and domain names etc.

A third important thing that should be of concern is that never open any unidentified emails in your email account. Whenever you open any unidentified email, it is a high probability that it could be a scam mail that exposes you to a hacker’s website and would allow access to all the information stored in your computer.

In addition, you should always remain disconnected from the internet, when it is not being used. This lessens the chance of hackers and intruders to get into your internet security.

You should also regularly update your security patches. Computer programs sometimes contain bugs that can be an entrance to your computer for any intruder to attack and potentially harm your computer.

In this way, you can potentially create a secure environment inside your computer the moment your are connected to a network or the internet.

Computer Network Security is essential nowadays for big organisations, banks and educational institutions. All these organisations use computer networks extensively and therefore need to secure their networks from hackers and other network infiltrators effectively.

There are lots of reasons why the data in big companies need to be secured. For example, the data that is shared across big companies in different countries need to be made secure from any internal threats or by non-trustworthy company employees. Moreover, there have been many instances where the passwords are easily hacked and companies find out until it is very late.

The external threats with regard to network security include planting Trojans, viral attacks and interception of viral data. And with wide expanding networks and businesses, the risk of being hacked and being vulnerable becomes even more.

When one thinks about getting secure computer networks, there is no single solution that one might think of. There are numerous solutions from which you have to choose yourself as to what shall fit to your network on the whole. To secure your company’s network, you can use encrypted pages, firewalls, different anti-hacking software and password.

As far as the security passwords are concerned, you should make sure that the passwords are hard to break. For this reason you have to keep a few things in mind:

a) The password should be long which means it should contain many characters

b) It should also be non-alphanumeric, that is, containing characters such as !,@,$,*.

c) The password should be random, i.e. more like being a jumbled word and should never have your name, family name or any other associated name or else it will be easily cracked

Virus attacks are most common security threats to your computer. They can easily enter your computer without you even knowing about it. This mostly happens when you are connected to the internet. For this you might have to install anti-virus software or network security software.

The fact that various network security solutions are available and this indeed is a blessing for all those who don’t want their networks to be hacked, but with technology changing too fast, the organisations just cannot resort to one kind of network security software. However, getting the latest encryption schemes is a very important mission for those who develop these solutions.

Data encoding has become a challenge with changing times and technology. This is because the data that needs to be encoded is usually in obsolete form and to develop compatible software for already existing data is a difficult job. Thus, intelligent human administration is required as well. Obviously, it would not be wise to leave everything onto the security software, but to make a human effort is equally important.

Thus, the task of ensuring a secure computer network is indeed challenge and rather a battle that needs to be tackled at all costs.
