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.

Malware

In the past, viruses were created with the sole purpose of wreaking havoc on the infected systems. A large fraction of today’s malware, on the other hand, are designed to generate revenues for the creator. Spyware, botnets, and keyloggers steal information from your system or control it so that someone else can profit. In other words, the motivation for making them is now more attractive than before.

Keyloggers can reveal your usernames, passwords, PIN numbers, and other authentication information to their creators by recording your key strokes. This information can then be used for breaking into various accounts: credit cards, payment programs (like PayPal), online banks, and others. You’re right, keyloggers are among the favourite tools of individuals involved in identity theft.

Much like the viruses of old, most present day malware drain the resources, such as memory and hard disk space, of contaminated systems; sometimes forcing them to crash. They can also degrade network performance and in extreme cases, may even cause a total collapse.

If that’s not daunting enough, imagine an outbreak in your entire organisation. The damage could easily cost your organisation thousands of euros to repair. That’s not even counting yet the value of missed opportunities.

Entry points for malware range from optical disks, flash drives, and of course, the Internet. That means, your doors could be wide open to these attacks at this very moment.

Now, we’re not here to promise total invulnerability, as only an unplugged computer locked up in a vault will ever be totally safe from malware. Instead, this is what we’ll do:

  • Perform an assessment of your computer usage practices and security policies. Software and hardware alone won’t do the trick.
  • Identify weak points as well as poor practices and propose changes wherever necessary. Weak points and poor practices range from the use of perennial passwords and keeping old, unused accounts to poorly configured firewalls.
  • Install malware scanners and firewalls and configure them for maximal protection with minimal effect on network and system performance.
  • Implement regular security patches.
  • Conduct a regular inspection on security policy compliance as well as a review of the policies to see if they are up to date with the latest threats.
  • Keep an audit trail for future use in forensic activities.
  • Establish a risk management system.
  • Apply data encryption where necessary.
  • Implement a backup system to make sure that, in a worst case scenario, archived data is safe.
  • Propose data replication so as to mitigate the after effects of data loss and to ensure your company can proceed with ‘business as usual’.

Once we’ve worked with you to make all these happen, you’ll be able to sleep better.

Understanding Carbon Emissions

Carbon emission is one of the hottest issues in the world of energy and environment today. While it is supposedly an essential component of the ecosystem, it has already become a large contributing factor to climate change. Carbon emission might be good but abuse of this natural process has made it harmful to people across the globe.

This series of articles aims to help people understand the intricacies of carbon emission and what society can do to efficiently manage this natural occurrence.

Natural Carbon Cycle

Two important elements in the carbon cycle are carbon, which is present in every living thing all over the world; and oxygen, which is found in the air that people breathe. When these two bond together, they create a colourless and odourless greenhouse gas known as carbon dioxide, which is then crucial to trapping infrared radiation heat in the atmosphere and also for weathering rocks.

Carbon is not only found in the atmosphere of the earth. It is also an element found in oceans, plants, coal deposits, oil and natural gas from deep down the earth?s core. Through the carbon cycle, carbon moves naturally from one portion of the earth to another. Looking at this scenario, one can see that the natural carbon cycle is a healthy way to release carbon dioxide into the air in order to be absorbed again by trees and plants.

Altered Carbon Cycle

The natural circulation of carbon among the atmosphere is vital to humankind. However, studies show that humans misuse this natural cycle and abuse it instead. Whenever people burn fossil fuels such as coal, oil and natural gas, they produce carbon dioxide ? which is an excess addition to the natural flow of carbon in the environment. The problem is that the release of carbon dioxide is much more than what plants and trees can re-absorb. People are not only adding CO2 to the atmosphere, they are also influencing the ability of natural sinks, such as forests, to remove it from the atmosphere. Humans alter the carbon cycle by contributing doubled or tripled greenhouse gas to the atmosphere, faster than nature can ever eliminate. Worst, nature?s balance is destroyed.

The Result

Greenhouse gases include carbon dioxide, methane, nitrous oxide, fluorinated gas and other gases. Although these gasses contribute to climate change, carbon dioxide is the largest greenhouse gas that humans emit. The reason why people talk about carbon emissions most, is because we produce more carbon dioxide than any other greenhouse gas.

The increasing amount of carbon emissions cause global warming to become more evident. All the extra carbon dioxide causes the earth?s overall temperature to rise as well. As the temperature increases, climate also changes unpredictably. Flood, droughts, heat waves and hurricanes are now widely experienced even in places where these phenomenon never used to happen.

To be able to reduce the risk of more severe weather conditions means burning less fossil fuels and shifting more to renewable sources. This is never easy. But, definitely, it’s worth a try.

UK Government Updates ESOS Guidelines

Britain?s Environment Agency has produced an update to the ESOS guidelines previously published by the Department of Energy and Climate Change. Fortunately for businesses much of it has remained the same. Hence it is only necessary to highlight the changes here.

  1. Participants in joint ventures without a clear majority must assess themselves individually against criteria for participation, and run their own ESOS programs if they comply.
  2. If a party supplying energy to assets held in trust qualifies for ESOS then these assets must be included in its program.
  3. Total energy consumption applies only to assets held on both the 31 December 2014 and 5 December 2015 peg points. This is relevant to the construction industry where sites may exchange hands between the two dates. The definition of ?held? includes borrowed, leased, rented and used.
  4. Energy consumption while travelling by plane or ship is only relevant if either (or both) start and end-points are in the UK. Foreign travel may be voluntarily included at company discretion. The guidelines are silent regarding double counting when travelling to fellow EU states.
  5. The choice of sites to sample is at the discretion of the company and lead assessor. The findings of these audits must be applied across the board, and ?robust explanations? provided in the evidence pack for selection of specific sites. This is a departure from traditional emphasis on random.

The Environment Agency has provided the following checklist of what to keep in the evidence pack

  1. Contact details of participating and responsible undertakings
  2. Details of directors or equivalents who reviewed the assessment
  3. Written confirmation of this by these persons
  4. Contact details of lead assessor and the register they appear on
  5. Written confirmation by the assessor they signed the ESOS off
  6. Calculation of total energy consumption
  7. List of identified areas of significant consumption
  8. Details of audits and methodologies used
  9. Details of energy saving opportunities identified
  10. Details of methods used to address these opportunities / certificates
  11. Contracts covering aggregation or release of group members
  12. If less than twelve months of data used why this was so
  13. Justification for using this lesser time frame
  14. Reasons for including unverifiable data in assessments
  15. Methodology used for arriving at estimates applied
  16. If applicable, why the lead assessor overlooked a consumption profile
