Internal and External Strategy for Network Security

Basically, the strategy to secure your business office network can be divided into the internal and external network security strategy.

Internal strategy to secure the network

Implement Backup and Disaster Recovery Procedures: Core business data is the lifeblood of any business. Implementing a multilevel backup procedure; image, file and folder, and offsite, is a simple way to protect critical data. Backup and Disaster Recovery (BDR) appliances take this a step further by helping you quicken server recovery in case of failure. Testing your backups periodically is an important component of any backup strategy.

Implement Desktop and Server Virus Protection: These software solutions have been around for a long time and they continue to evolve as threats evolve. Keep your anti-malware software current and its definitions current.

Patch Desktops and Servers Regularly: Security vulnerabilities in the operating system and in applications are regularly addressed by reputable software vendors. Take advantage of them. Keeping security patches current from your software vendors protects your computer from known attacks and vulnerabilities. Again, there are centralized patch management tools that make the process less time consuming.

Centralize Computer Administration: By implementing a server and applying a group policy across computers, you can standardize the process and save each user the time it takes to implement configurations one computer at a time. There are tools to centrally manage virus updates, security patches, desktop firewall, permission groups, and other security features.

Secure Physical Access: Do not overlook the physical location of your critical network infrastructure. These should be accessible to trained and trusted employees. Keeping this infrastructure secure in a locked room or server closet will reduce inadvertent or fraudulent access or change to network.

Secure WiFi Access: WiFi access to the network enables even mobile employees to be productive. Data, as it travels over the air is typically less secure than when it travels over wired networks. Information traveling over the air is at risk of interception. Use wireless data encryption protocols to ensure that data is encrypted during transit from source to destination to protect against risk or interception. Also, the company need to setup wireless access point for guests on a separate subnet. So they can access the Internet but not your network.

External and perimeter strategy to secure the network

Consider Outsourcing Email Services: Corporate email has become mission critical for businesses of all sizes. If you do not have a mission-critical application support infrastructure internally, consider outsourcing your email infrastructure. The widespread availability of such solutions from key industry vendors makes these affordable. And you can leave the worry of securing and maintaining such infrastructure in the hands of those that do it 24×7.

Secure the Perimeter: Connecting your network to the Internet allows you and your employees to gain access to valuable data and be productive even when on the run, but it also exposes your network to attack from intruders. Most small businesses use consumer grade routers/firewalls to protect the edge of their network that is right behind the broadband modem.

Though these devices have grown in functionality, they aren’t equipped to handle the perimeter security needs of a business. With business grade routers/firewalls/UTM (Universal Threat Management) appliances, you gain a powerful hardware platform that provides ability to filter malicious traffic and spam from the outside, receive regular security updates, provide secure remote access, implement intrusion detection and prevention services, and prevent infectious code from executing from trusted but compromised sites.

Stay Informed and Vigilant: There are numerous industry and government sites dedicated to network security. Stay informed as data and practices continue to evolve. Business-grade UTM appliances are designed to be monitored remotely from security operations centers and to send reports and alerts that may need attention.

User Friendly Technology for Patient

Patient Friendly TechnologyIn this electronically, technologically challenging era, there are some strides being made which actually are helpful and hopeful. New solutions for a better quality and longer life are being developed at the MIT Age Lab in Cambridge, Mass. Founded in 1999; technological advancement is their reason for being.

A recent focus for development has been finding ways to monitor the eating habits of senior citizens, tracking how and when medication and supplements are taken, and fulfilling the need for interaction with other people. NASA had a system for communicating with the astronauts when they were in space. Could this same system be as effective in meeting the needs in question?

A touch-screen videoconferencing computer was installed in a volunteer’s kitchen, sending the pertinent data directly to the family’s waiting computer. Not only could they find out that Grandma actually had eaten, they could discuss what she had eaten in a lively, interactive, after-breakfast chat. So, although Grandma was initially apprehensive about the change, technology proved to be a friend.

Elsewhere in scientific circles, like-minded researchers are engaging in similar experiments and enjoying similar, encouraging results. In Rochester, Minn, the Healthy Aging and Independent Living (HAIL) Lab interacts with a continuing care retirement center called the Charter House. This community is connected to the Mayo Clinic and is where the lab is located.

Once again, the concerns being addressed were tracking medication and interaction with the elderly, in particular those with chronic diseases. Was the person with diabetes or hypertension taking their supplements? If there was a problem, could communication be established between patient and health coach to handle the problem at the time it was happening?

Researchers had tablet computers with video messaging installed in volunteer’s apartments. They were given wireless blood pressure cuffs so their tablets could record their blood pressure information. With an elevated level, a health coach can engage in a live chat with the patient on a remote computer, finding out exactly what is happening, and giving instructions to follow.

At the time of medication for hypertension, the user tells the tablet, and this ingenious device not only displays the blood pressure information, but it shows a picture of the entire circulatory system, and the effect the medication is having on the body.

Another concern researchers had was whether or not patients would object to, or be annoyed by, a cardiac sensor on the chest. This Band-Aid-size transmitter would feed pertinent heart-care information to a healthcare team. In both cases, with the tablet and the sensor, participants not only didn’t mind the equipment, they enjoyed having a part in their health care.

They were able to see for themselves how their medication worked, and what would happen to them if they didn’t take it. Here again, what researchers hoped would happen, did happen. Not only did technology accomplish the intended goals, but the patients accepted the new treatment as a valuable asset.

The Advantages and Disadvantages of Ubuntu

UbuntuUbuntu is currently the most popular Linux distribution and when somebody is talking about Linux, very likely that he is talking about Ubuntu. There are mix complicated opinions toward Ubuntu. In this article, we will enumerate the advantages and disadvantages of Ubuntu.


Ubuntu has a lot of advantages to offer to its users. First of all, it is designed to be very easy to use and install. One of its strongest selling points is that Ubuntu will detect all your hardware, set up your networking, and allows you to easily configure your operating system through a nice pretty and shiny brown purple interface.

That is why former users of Ubuntu will still feel comfortable in the environment of Ubuntu. The other good thing about Ubuntu is that it is supported very well. It seems that when someone talks about Linux Support these days it means Ubuntu more than any other distribution.

The ability to install .deb file makes it very easy to obtain and install certain software. Besides, Ubuntu is back up by Canonical, a huge company with strong capital. More than that, the user community of Ubuntu is the largest among the Linux world. And last but not least, Ubuntu has a large collection of applications available in its repository so users will be able to find all the software they need.


However, nothing is totally perfect. Ubuntu has its disadvantages as well. Ubuntu is designed to be easy to use for newbies. So if the users want to try to do something advanced, they may end up fighting the whole operating system.

For example, if you want to switch to a new desktop environment other than the default one, you will have a lot of bugs and errors to deal with. It is very difficult to tweak and customize the default settings in Ubuntu, many users have been complaining about the network settings and the audio configuration of Ubuntu.


The Ubuntu community is the largest in the Linux world nowadays but it consists mostly of new users so you can get a lot of bad advice from there. Many of the solutions for simple problems involve downloading new packages, which will bloat of your system, instead of properly fixing it. It is very annoying to have to download a huge chunk of new packages just to fix a tiny problem.

App Development Companies

App DevelopmentApplication development refers to the formation of a computer program that is controlled behind the scenes via a source code. This role is usually played by app development companies. Apps are mainly required by small and big organizations in their executive functions such as stock inventories, asset tracking, social networking, ticket booking, bookkeeping and accounting among others.

Apps development consists of various sections including, mainly, the mobile application. It can be described as the procedure through which application software is created for mobile phones and other handheld devices. Mobile apps are highly preferred by various organizations to ensure efficient and timely communication with their worldwide clients.

They are usually added to a hand-held system like a smartphone to have features such as 3D games, tickets booking, shopping carts, social networks, payment gateways and GPRS road maps among other things.

There are different supported platforms such as Blackberry, iPad, iPhone, Windows OS and Android among others. App development companies aim at helping their clients boost their Return on Investment (ROI) through their matchless services. With their innovative development function spanning all industries, these developers strive to make apps that are compatible with the mission and vision statements of any company.

Android application development is another popular section within of the services offered by these companies. Most of them do custom Android applications to allow their customers have the designs of their choice. Other Java-based Android service delivery choices include games development, multimedia mobile solutions, mobile business software, Wi-Fi and GPS solutions, Bluetooth support, 2D and 3D graphics library building and internet-based apps.

The best app development companies use professional workers who are familiar with the Android API (Application Program Interface) and SDK (Software Development Kit) so as to create high utility applications. They are conversant in Windows Vista, Windows XP and Linux Operating Systems.

Android companies’ workers have familiarity with Java, C and C++ programming languages too. The key methodologies used include Waterfall, Agile and Rapid Action Development.The iPad or iPhone application development is a rather common area of expertise that numerous app development companies dwell on.

The iPhone and iPad are two awesome platforms for any kind of work that involves development of customer-friendly and interactive features. They are applied in different areas such as website development, widgets creation, socio networks integration, creation of travel aids like weather forecasting and GPRS navigation maps and business solutions such as payment gateways and shopping carts. The iPhone application developers are proficient in the well-known Apple iOS platform. They also know other technologies like Objective C, Xcode, Javascript, iPhone SDK, AJAX, and XHTML.

The Blackberry apps are very widespread nowadays. Blackberry happens to be one of the most precious platforms for creating intricate business functions that consists of a blend of graphics and multimedia apps. The main services created by developers in this area include GPS and navigation tools, communication tools, 3D gaming solutions and web and system applications.

Technologies such as HTML, Java, C++, CSS and J2ME are mainly applied in the formation of Blackberry software applications. There are several app development companies that participate in application development today. This, however, does not mean that each company is trustworthy enough to handle small or big projects.

It is very important to locate a reliable and reputable apps provider in one’s country or somewhere else in the world. When attempting to select the best software development company, customers should focus on the years of experience and level of success it has achieved so far.

Improving Your Network Security

When computer networks were isolated within the walls of offices, an Internet connection was a luxury and not a critical component of business functions. That has now completely changed for businesses that rely on computers to acquire and deliver services.

Customers, business partners, remote office locations, and mobile workers expect connectivity to your office network. This interconnected nature of networks opens doors to new levels of productivity; and to threats that can disrupt business.

Securing your network should not be an afterthought; it just makes business sense. The benefits of a secure network are numerous:

It is more reliable, has fewer problems, and consequently costs less to maintain.
Improves productivity across all your stakeholders: customers, partners, and employees.
Protects your investment in bandwidth by controlling abusive use and unwitting hosting.
Reduce your exposure to legal and regulatory action.

Employee education and policy strategy

Provide Security Training: All employees, includes managers and executives, should be educated on basic security practices and how to protect sensitive business information. Establish policies and rules, including penalties for violating them, on how to protect sensitive data and make training available on a regular basis.

Topics include: whether and when to use Web for personal use on office computers, instant messaging, social networking sites, streaming video and music, if and how company monitors Web usage, prohibited activities, tips for safe browsing, common techniques used by hackers and how to avoid falling prey.

Use Strong Passwords: Passwords are the most common method for gaining access to network resources. Unfortunately, they are also easy to hack through the use of automated tools. Train staff to use their passwords as they would their home keys: don’t leave them lying around and don’t share them. Strong passwords typically use a combination of letters, numbers and symbols, are at least 8-characters long, are changed every quarter, and differ significantly from previous passwords.

Regulate Access to Information: You probably don’t want to give everyone full access to everything. The judicious use of network user groups and permissions ensure network resources and data are available on a business need basis and that the Administrator account is only provided to trusted resources and executives and used only when necessary. Many line-of-business applications support roles, such as Sales, Operations, Accounts Payables, etc. to provide access to data they maintain on a business need basis.
