Firewalls

There are two main reasons why some companies are hesitant to plug into the Internet.

  1. They know they’ll be exposing their company data to outside attacks from malicious individuals and malware.
  2. They fear their employees might get too many distractions: games, porn, chats, videos, and even social networking sites.

One vital component for your overall security strategy against such concerns? A firewall.

A firewall can block unauthorised access to certain Internet services from inside your organisation as well as prevent unauthenticated access from the outside. It is also used to monitor users’ activities while they were online.

In an enterprise setting, one may expect a collection of firewalls either for providing layered protection or segmenting off different units in the organisation. Some areas only need a standard line of defence while others require more restrictions. As such, certain firewalls may have different configurations compared to others.

Naturally, the more intricate an organisation’s defence requirements get, the more complex the task of monitoring, testing and configuring the firewalls becomes. That’s why we’re here to help.

  • We’ll evaluate your network as well as the security requirements of each department under your organisation to determine which firewall architecture is most suitable.
  • To achieve maximum efficiency, we’ll point out where each firewall should be positioned.
  • We’ll work with your key personnel to make sure all firewall configurations are set and optimised with your business rules in mind.
  • If a large number of firewalls are required, we’ll help you set up a firewall configuration management system.
  • Firewalls should be regularly tested and assessed to ensure they are in line with the organisation’s security policies. We’ll perform these routine tasks as well.

Firewalls aren’t very good at defending against sophisticated viruses. There are much better solutions for malware-related vulnerabilities, and we can help you in that regard too.

Other defences we’re capable of putting up include:

How Volvo Dublin achieved Zero Landfill Status

The sprawling New River Valley Volvo plant in Dublin, Virginia slashed its electricity bill by 25% in a single year when it set its mind to this in 2009. It went on to become the first carbon-neutral factory in 2012 after replacing fossil energy with renewable power. Further efforts rewarded it with zero-landfill status in 2013. ecoVaro decided to investigate how it achieved this latest success.

Volvo Dublin?s anti-landfill project began when it identified, measured and evaluated all liquid and solid waste sources within the plant (i.e. before these left the works). This quantified data provided its environmental project team with a base from which to explore options for reusing, recycling and composting the discards.

Several decisions followed immediately. Volvo instructed its component suppliers to stop using cardboard boxes and foam rubber / Styrofoam as packaging, in favour of reusable shipping containers. This represented a collaborative saving that benefited both parties although this was just a forerunner of what followed.

Next, Volvo?s New River Valley truck assembly plant turned its attention to the paint shop. It developed methods to trap, reconstitute and reuse solvents that flushed paint lines, and recycle paint sludge to fire a cement kiln. The plant cafeteria did not escape attention either. The environment team made sure that all utensils, cups, containers and food waste generated were compostable at a facility on site.

The results of these simple, and in hindsight obvious decisions were remarkable. Every year since then Volvo has generated energy savings equivalent to 9,348 oil barrels or if you prefer 14,509 megawatts of electricity. Just imagine the benefits if every manufacturing facility did something similar everywhere around the world.

By 2012, the New River Valley Volvo Plant became the first U.S. facility to receive ISO 50001 energy-management status under a government-administered process. Further technology enhancements followed. These included solar hot water boilers and infrared heating throughout the 1.6 million square foot (148,644 square meter) plant, building automation systems that kept energy costs down, and listening to employees who were brim-full with good ideas.

The Volvo experience is by no means unique although it may have been ahead of the curve. General Motors has more than 106 landfill-free installations and Ford plans to reduce waste per vehicle by 40% between 2010 and 2016. These projects all began by measuring energy footprints throughout the process. ecoVaro provides a facility for you to do this too.

Saving Energy Step 5 – Bringing it together

We hope you have been enjoying our series of short posts regarding saving energy, so what we use we can sustain. We have tried to make a dry subject interesting. After you read this post please comment, and tell us how it went. We are in the environment together. As the man who wrote ?No Man is an Island? said, ?if a clod be washed away somewhere by the sea, Europe is the less? and Europe was his entire world.

The 4 Steps we wrote about previously have a multiplier effect when we harness them together

  1. Having a management system diffuses office politics and pins accountability in a way that not even a worm could wriggle
  2. This defines the boundaries for senior managers and empowers them to implement practical improvements with confidence
  3. The results feed back into lower energy bills: this convinces the organisation that more is possible
  4. This dream filters through all levels of the organisation, as a natural team forms to make work and home a better place.

None of this would be possible without measuring energy consumption throughout the process, converting this into meaningful analytics, and playing ?what-if? scenarios against each other to determine where to start.

The 5th Step to Energy Saving that brings the other four together can double the individual benefits as innovative power flows between them. The monetary savings are impressive and provide capital to go even further. Why not allow us to help you manage what we measure together.

ecoVaro turns your numbers into meaningful analytics, makes suggestions, and stays with you so we can quantify your savings as you make them. We should talk about this soon.

Solutions to Password Overload

If only technologists had their way, passwords and PINs would have long been replaced with more innovative (and admittedly, better) security solutions. But such is not the case. Those alternative solutions, which include biometrics, smart cards, and password fobs, effective as they may be, are just way too expensive to implement.

So although passwords and PINs may not be here to stay, they certainly won’t be going away soon either.

Why keeping passwords in memory is no longer possible

A couple of decades ago, it would have been nearly impossible to crack an eight-character password using brute force. Today, however, advancements in computing power are rendering the typical passwords of the past easily decipherable, forcing us to come up with passwords that are not only much longer, but also much more complex and hence difficult to recall.

For instance, memorable words like your favourite character (e.g. ‘skywalker’) may have been acceptable then, but not anymore. Today?s security systems will encourage you to insert numbers or even other keyboard characters as a means to once again counter brute force. Hence, ‘sk5%ywa936lker@#’ may be more acceptable.

Remembering that one alone can be pretty daunting.

To further complicate matters, the number of applications that require passwords for access is much greater than before even for a single end user. Ordinary end users have to keep track of passwords for their email account, network login, workstation login, online services, and so on.

The burden is even greater for your IT admins, who have to remember a larger collection of passwords that protect business critical systems and applications. Clearly, the team in charge of your IT security will need a way to manage all these passwords.

Password management solutions

Existing password management solutions typically come in the form of software applications that store passwords. Basically, all you need to remember are your login details for the app a.k.a. the ?master password?. Once you’ve gained access inside, you can then retrieve any password you stored there.

Some of these apps are installed in portable devices like Pocket PCs, PDAs, or smartphones, which you would normally take along with you. For as long as the device stays with you, your passwords will be in safe hands. What’s more, you can retrieve them anywhere you go.

But obviously, there’s a problem. What if the device gets misplaced or stolen? Although the person who ends up with your device may not be able to gain access into the app and your passwords, neither will you. A better solution would therefore be an app that can be accessed anywhere but is not susceptible to getting lost.

Web-based password manager

A web-based password manager fits the bill. You don’t have to take it with you, but still you can access it almost anywhere. A typical web-based password manager will have all your passwords stored in a centralised, highly secure location.

If you want, you can even use your mobile password manager along with the web-based one. Ideally, your web-based password manager would have a copy of all the end-user passwords as well as the master passwords of your organisation.

With an easy to access but highly-secure web-based password manager, you no longer have to come up with passwords that (ironically) are supposed to be easy to remember but hard to crack at the the same time.

Furthermore, password managers are ideal for keeping passwords that have to be changed every-now-and-then; a requirement that’s becoming all too common in organisations bent on enforcing more stringent controls.
