Tips for Network Security
Jan 31st
Network in nowadays give us possibilities communicate and do more other things possible and much faster. But not everything is so nice how we thing in first moment. There are a lot of threats which grow up every day in networking!
Here are 10 information security awareness tips for network security, which helps to do network and communication via this network safer, and also give to you confidence that everything is O.K.
1.Use strong password.
Passwords are the simplest form of security. By leaving passwords blank or simple (i.e., password or admin), unauthorized users are practically invited to view sensitive data. Passwords are more secure when they contain letters,numbers and special characters in a combination of upper-case and lower-case characters, and they should be changed periodically.
2.Educate users.
Users need to know exactly what kinds of threats they can expect using e-mail, making faceless downloads and open unknown attachments. Uneducated computer users are often those who fall victim to viruses, spyware, and phishing attacks, all of which are designed to corrupt systems or leak personal information to a third party without the user\’s consent. The best way hot to make this education is to do special information security awareness training which provides some companies, for example, InfoSecurityLab.
3.Make backup copies.
Indulence is one of the biggest security threats. It\’s considerably more difficult to completely re-create a crippled system than it is to take the time to create proper backups. Create backups often, and do not immediately overwrite them with the next set of backups. In addition, make copies and keep them off-site in case of emergency.
4.Use protection software.
Network Security: The Risks of Having an Unsecured Network
Jan 30th
One of the reasons why it is necessary to make sure that your network is fully secured is to ensure that it cannot be hacked or any of your information passed on to third parties; this is primarily because extremely important information will invariably be passed from one computer to another computer, within the network during a working day. If the network is not secure at the logical as well as the physical level, one is definitely not going to know that important information is being funneled through channels up on the Internet to possibly your rivals as well as your competition.
That is the reason a good network security company is going to make sure that every single security tool and other necessary features, such as firewalls, are in place. Fundamentally, the primary reason for doing all of this is quite simply to protect your hardware as well as the data to the best of your ability. The way in which this is carried out, including the methods and tools is all very much dependent on the network that you have and what your business requirements are.
An unsecured network on which internal management as well as external penetration and hacking tests have not been done are definitely a security hazard for any company out there. That is the reason why a company’s key assets need to be protected in the strictest manner possible.
One of the most biggest risks about having an unsecured network is that the moment you go online on an http:// (including intranet) connection, there is a chance of every sort of vital information being transferred from your computer. In the same manner important information can be downloaded straight from your different hard drives, just because some other computer has managed to bypass your security measures. That is one of the more risky aspects of working on a computer on an unsecured network.
Network Security Solutions: Obstacles in IT transformation?
Jan 28th
IT synonyms transformation and it is imperative that enterprises treat transformation as a continuous process. But, a significant obstacle to all of this transformation and differentiation is the absence of sufficiently capable network security solutions.
Growth in Network Traffic and Threats
One of the major changes impacting the effectiveness of network security solutions is the growing volume and sophistication of network traffic, which subsequently reduces operational efficiency. The rising speed of business is practically dictating an increased pace of development and deployment of new applications to support both back office and customer-facing processes.
In past, we were concerned about file level viruses and worms that have been overshadowed by an array of new contenders, which include spyware, spear phishing, key logging Trojans, root kits and targeted attacks. Even more troubling is the trend of threats migrating up the stack to take advantage of much harder to protect application-layer weaknesses.
Network Security Infrastructure
The challenges outlined reveal the minimum set of requirements for an appropriate network security solution for an enterprise’s most rigorous use cases. Specifically, a solution must fully address the following set of essential criteria.
Security: It must provide protection for not only at the network layer, but at the application layer and for individual elements of data as well. Firewall technology is simply not sufficient.
Scalability: System capacity must be readily scalable from relatively modest traffic rates of a few Gbps to an aggregate throughput of greater than 100 Gbps.
Latency: Solutions must be architect to minimize the amount they introduce and should also incorporate capabilities to prioritize the processing of designated, time-sensitive traffic streams.
Unified management: Administration of the solution’s various capabilities should not require the use of multiple management tools or consoles.
Reliability, adaptability and compatibility: The solution must fulfill the expectations and supports for a wide range of networking technologies such as NAT, address assignment, VLANs, and security zones.

Networking Security Threats
We as individuals interact with networks in our daily activities whether in the office, at home, or when we perform monetary transactions, use our mobile phones to make calls or use transport systems to get to work. Today, telecommunication and utility companies use networks to track phone, electricity or water usage and bill for it. Government agencies and organisations depend heavily on networks to communicate with their customers in areas such as credit or debit card transactions and billings. Many of our basic ways of life would be less convenient and many activities would be unfeasible without networks. Not astonishingly, network systems are criminals and intruders targets of choice, because of their potential vulnerabilities.
What makes a network vulnerable?
Connecting computer systems together is incredibly risky due to potential system misconfiguration, poor security policies and software flaws. Criminals can gain unauthorised access to remote networks. Intruders can capture transmissions between network nodes. Furthermore, linking networks enables organisations and individuals, including criminals, to communicate in ways that were not feasible before, resulting in a new set of vulnerabilities. Misuse of newly discovered vulnerabilities by intruders often catches us unaware. There is a need to keep information systems and the networks which carry the associated information or data secure. There are many names for these, from networking security to information assurance. The overriding set of principles are those of C I A (Confidentiality, Integrity, Availability), which are considered by many to be the tenets or principles of computer security. Digital assets include the entire network infrastructure, system application programs including data.

A Quick Introduction to Network Security Measures
Jan 24th
The computer network is perhaps the most important system that is running within your company. Your network powers almost everything that the computers do – from daily essential tasks like email to surfing on the Internet, sharing documents, sharing printers, etc. So if your network happens to be down, the entire organization is greatly inconvenienced. Lots of man hours would be wasted. And if the network is down repeatedly, productivity will decline.
There are many reasons that may cause a network to be down. We are talking about network security issues here. Minor network security breaches involve attack on the personal workstation. For example, a workstation may be infested with viruses or spyware. Viruses and spyware are types are software that operate mostly in the background. They are usually installed on the computers without the permission of the user and perform malicious operations such as hijacking browsers or wiping out hard disk drive data.
More serious network security breaches involve real time attack on the servers. As the servers power many important functions of the network (e.g. sending or receiving email, or storing confidential company data), the consequences are disastrous if servers have been compromised. The general term for server attacks is known as “intrusion”.
Earlier, we have briefly discussed how a personal workstation can be compromised by viruses or spyware. This is also a form of intrusion on the personal computer. This form of intrusion is usually passive. In other words, it may involve some action from the user in order for the software to be installed. For instance, the user may be browsing malicious websites, or an individual may have installed a virus accidentally, thinking that it was an innocent game.
