You might have come across a lot of app securities out there but you might not have known what they are all about. To make sense of an application type of security, understand that it makes the most of procedural methods, hardware and software to ensure applications have been protected from all kinds of external threats.

Online Security - Who Do You Trust?

Internet security is a branch of computer security specifically related to the Internet, often involving browser security but also network security on a more general level as it applies to other applications or operating systems on a whole. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet represents an insecure channel for exchanging information leading to a high risk of intrusion or fraud, such as phishing. Different methods have been used to protect the transfer of data, including encryption.

How to Have the Best Computer Passwords

In today age of inter connectivity where almost everything can be stored and access via the internet, one important aspect of storing our things behind lock and keys is the PASSWORD. Yup the old fashion lock and key has a digital equivalent called the PASSWORD. The PASSWORD is one of the most important aspect of security for keeping safe our files. We often used them in our computer so we lock the computer itself or put a password on the account that we used to log-in into our computer.

No sane person would ever like somebody else reading her email, or logging into their computer and swiping their allegedly secure search engine optimization information. Or for what it's worth some other person using her password and breaking into a monetary institution. You should, choose a powerful, secure password in such a manner that will be a hard nut to crack for others and easy for you to recollect. The more random and mixed-up you make it, the harder it is for others to break. Mind you, if your password is compromised, the password crackers will even take over your identity.

The password that we use to access all our account can be the same or every bit different from each account. If we use different password in all of our account then we need to write down or use a password manager. A password, if too short, is vulnerable to attack if an attacker gets hold of the cryptographic hash of the password. Present-day PCs are fast enough to try all alphabetic passwords shorter than 7 characters. We will be able to call a password puny if it is short or is a default, or which can sometimes be rapidly guessed by searching a subset of all possible passwords such as words in the compendium, correct names, words based totally on the user name or common variations on these themes.

On the other hand, a robust password would be sufficiently long, random, or which can be produced only by the user who chose it, so that ‘guessing ‘ for it will require too long a time.

For maximum security, the user should follow some simple guidelines:

1) Passwords should preferably be at least 8 characters long and not more than 14.

2) Passwords should contain a mix of numbers, letters, and special characters (%&3ac_ht4m7).

3) Passwords shouldn't contain a compendium word from any compendium, be it French, Spanish, medical, etc.

4) Each password should be different from the user’s User-ID and any permutation of that User-ID.

5) New passwords and old passwords should differ by at least 3 characters.

6) Avoid picking names or nicknames of folk, pets, or places, or personal info that may be simply found out,eg your birthday, address etc.

7) It’s sensible to stay away from common keyboard sequences,eg dfgh678 or abc345.

8) Never form a password by appending a digit to a word. That can be simply guessed.

9) Avoid writing your password down or storing it on your PC.

10) Never share your password with any other person.

Making sure that our password is safe and is hard to guess is just one of the many ways of keeping our digital information safe. We must also be very careful in using our computer in public places  or using public computers, because we never know what who or what kind of application is watching us input those very sacred alpha numeric combination. We must always be vigilant in everything that we do whenever we are logging in into our account wherever we may be.

The Basic Function of a Computer Firewall

The word firewall is a very term in the world of computing. It is a part of a security of a computer or network but for today’s topic where going to focus a personal computer firewall. First what is a computer firewall, well it could be a software firewall or hardware firewall, wait a minute here this is getting to deep before we go any further let’s see what a firewall in general do or how does it gets to function. Firewall checks information coming from the Internet or a network and then either turns it away or allows it to pass through to your computer, depending on your firewall settings. In this way, a firewall helps prevent hackers and malicious software from gaining access to your computer. Windows Firewall is built into Windows and is turned on automatically.

The firewall has different settings depending on its work areas. For a firewall of a personal computer the general setting is usually determine by the owner which program is allowed or denied access to computer. Allowing a program to communicate through the firewall, sometimes called unblocking, is when you allow a particular program to send information through the firewall. You can also allow a program to communicate through the firewall by opening one or more ports. If you run a program such as an instant messaging program or a multi-player network game that needs to receive information from the Internet or a network, the firewall asks if you want to block or unblock (allow) the connection. If you choose to unblock the connection, Windows Firewall creates an exception so that the firewall won't bother you when that program needs to receive information in the future.

The recommended general default firewall settings are listed below:

·         The firewall is on.

·         The firewall is on for all network locations (Home or work, Public place, or Domain).

·         The firewall is on for all network connections.

·         The firewall is blocking all inbound connections except those that you specifically allowed.

·         E‑mail viruses

The two items listed below are the two most common applications that a computer firewall can prevent from entering your computer. With the help of a properly set firewall the two items below can be prevented from infecting and gaining information from your computer.

E‑mail viruses

E‑mail viruses are attached to e‑mail messages. A firewall can't determine the contents of e‑mail messages, so it can't protect you from these types of viruses. You should use an antivirus program to scan and delete suspicious attachments from an e‑mail message before you open it. Even when you have an antivirus program, you should not open an e‑mail attachment if you're not positive it's safe.

Phishing scams

 

Phishing is a technique used to trick computer users into revealing personal or financial information, such as a bank account password. A common online phishing scam starts with an e‑mail message that appears to come from a trusted source, but actually directs recipients to provide information to a fraudulent website. Firewalls can't determine the contents of e‑mail messages, so they can't protect you from this type of attack.

If I have a router with a built-in firewall, should I also turn on Windows Firewall?

Yes, because router-based firewalls only provide protection from computers on the Internet, not from computers on your home network. For example, if a mobile computer or guest computer connects to some other network, becomes infected with a computer worm, and then connects to your home network; your router-based firewall won't be able to prevent the spread of the worm. However, a firewall running on each computer on your network can help control the spread of worms.

However, running more than one firewall program on your computer at the same time could cause conflicts. It's best to just use one firewall program, in addition to a router-based firewall.

Five Common Problems Overlooked By Business IT Networks

IT Networks though easy, need extensive planning to ensure equilibrium, yet we frequently encounter businesses that are acquainted with the critical role networking plays in the efficient functioning of their company.

Informed business entrepreneurs, seo marketers, and managing directors, often choose to upgrade their networking systems to suit their organizational structure. Though upgrading is an expensive, time consuming process, it's advantages are 10 fold. Though, there are some small size firms that insist strongly upon having a Windows XP workstation function as a network server, this decision may ultimately lead straight to drop off in efficiency and productiveness of the entire Information Technology environment.

Network Experts should investigate the character of your business in order to endorse a networking/Information Technology system that would be the best fit for your business. IT Experts should gauge both hardware and software requirements to lead your company thru the good points and bad points of various networking options that your business could be considering.

From a network consulting viewpoint, these are five general problems that are either neglected by companies or not included in the planning of the Network Infrastructure.

Disaster Recovery: Although entrepreneurs are risk takers they supply for all contingencies. While they insure their store and goods against fire, burglary, natural tragedies, etc, in many cases they ignore the need to commission a accident recovery plan for financial records, worker payroll and customer data. Losing valuable buyer information to a fire would lead to brief chaos and a monetary drain. Therefore, an information recovery system should be available to revive normal operation inside 24 to 48 hours. There are a few options to judge dependent on the scale of the business. A good Technology consulting company should be able to evaluate the needs and accordingly suggest an IT recovery plan that's idiot proof yet reasonable.

Redundancy: Though companies are advised to maintain an alternative or redundant energy source supply for critical servers, many entrepreneurs ignore this simple loss prevention system so as to save a few hundred greenbacks. As an example, servers that process customer credit card transactions aren't exempted from the likelihood of failure and if not backed by a redundant power source, it may lead to a major financial loss. The point that I am trying to get across is that important network equipment should be identified and a redundant plan should be implemented to provide against unforeseen circumstances.

Network Security: Viruses aren't strangers to the sector of computers and net. While performing technology research and checking we come across enterprises that have servers on DMZ without network safety measures like an easy firewall. We have seen examples were employees had total access to the network server running pathogen inviting programs like Limewire. An obvious result of this would be a slow network. Usually, passwords for workstations, servers and so on. Are identical and shared. Impermeable network security plans should be implemented particularly when business IT substructure holds confidential information of clients or people that will become a risk as well as an embarrassing situation if lost or nicked.

Network Speed: Companies always target maximizing potency and productivity at the smallest price and what better method to attain this goal than to minimize wastage of employee time? Speed of IT networks relies on many factors from straightforward network security policies to limit P2P software to intellectual switching hardware. You could be stunned but network infrastructure wiring (Moggy 5, Cat 6, and Fiber Optics) also makes a serious difference on the performance of the entire network.

Expandability: Change in networking structure is an option that should invariably be open for clients. To plan in advance is vital as a business need not overhaul a massive part of their network to see a unimportant benefit. An easy example is generally to expect network storage requirements of data. Clients frequently overlook the significance of discussing options with experts to make certain their IT system remains sufficient for a minimum of 3 to 5 years. The aim should be to decrease dollars spent without impeding the quality of work being performed by staff.

Advisers are professionals and while their suggestions should not be overlooked, they shouldn't be adopted blindly either. As a shopper you have entitlement to know the. ‘whys ‘ and ‘hows ‘ of every idea made. Request layman’s explanation for every problem faced. Most critically, make sure that the 5 major and basic areas are covered in the initial audit reports or suggestions made by any Technology consulting company.

How to Get a Secure Voicemail

Voicemail security is one of the things that is making headlines nowadays. This is because there are now more and more cases of hackers suddenly attacking both popular and regular individuals and trying to extract information from their voicemail accounts.

To help protect yourself, here are a few tips for being able to get a secure voicemail.

Image by spDuchamp via FlickrStrong Pin codes:

One of the responses that the telecommunications providers made to the threat of voicemail security and other phone line breeches was providing people with a way to utilize pin codes for account security. Previously, simply dialing the voicemail number would already connect you to your voice mailbox. However, the latest trend is to now ask users to input a pin code before they could start accessing their accounts.

Remember that pin codes would be useless for voice mail security if you would not provide a strong one. Try to utilize a combination of numbers and characters (if allowed) and not just rely on the basic series like 123456.

Do not give your number to just anyone:

A very basic method of getting a secure phone would be to not give away your personal number to anyone. If hackers would not have any direct access to your phone line, then they would have a very difficult time of having to guess around for your mobile number. This means that they would just rather try to target other people who they know are already active mobile phone users.

On the other hand, simply listing your numbers anywhere and everywhere would make it very easy for hackers and other unscrupulous people to target you and your voicemail account. If you would really need to publicize your number, we recommend getting both a public one and a private line.

Get a separate provider that offers voice-mail security:

The most secure your way that you can ensure that you have a secure voicemail would be by actually going with a company that offers you one. There are some companies who are able to provide you with a voice-mail account which use military grade encryption technology to make it difficult for hackers and other types of fraudsters to tap into your account.

This advanced capability of having a complex method for protecting your voicemail would be a major deterrent for people who are trying to get into your voicemail account and browse the messages that you have saved in there.
