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:

ESOS ? Why we must have it

The 9,000 big UK businesses directly affected by the new Energy Saving Opportunity Scheme could save UK?250 million between them, or an average UK?27,000 each, if they reduced electricity consumption by just 1%. The total amount is equal to the output of five power stations, at a time when Britain?s grid is under strain.
On 26 November 2014, UK Energy and Climate Change Secretary Ed Davey met with over 100 opinion makers from businesses, charities and universities at the Institute of Directors. The gist of what he presented was:

  • ?Britain?s big firms are spending around ?2.8 billion extra each year on inefficient energy technologies ? the equivalent output of nearly five power stations;
  • Now is the time to seize the opportunity with ESOS ? and organisations up and down the country are already gearing up to make changes to save energy, save money and save the environment.
  • If business did what business is supposed to do [that is innovate to make money] and act and invest, it will save ? and that’s the bottom line.?

The environmental benefits are as important although EcoVaro agrees with Ed Davey for taking a pecuniary approach. Businesses above the threshold of 250 staff and a balance sheet of UK?34 million would have not achieved their status unless they spent their money wisely.
The discussion panel included Rhian Kelly (Director of Business Environment at CBI), and Paul Ekins (Director UCL Institute for Sustainable Resources & Deputy Director of the UK Energy Research Centre). Hugh Jones, Managing Director, Advisory at the Carbon Trust responded to Ed Davey?s remarks by commenting:

  • ?At the Carbon Trust we have already engaged with hundreds of businesses on ESOS, helping to explain how they can achieve compliance while also making significant energy savings and cutting carbon.
  • Businesses often aren’t aware of opportunities in energy efficiency, or they don’t realise how attractive the paybacks can be. By requiring companies to understand exactly how they can make cost-effective investment in energy efficiency, they are far more likely to take action.
  • From the interest we have seen so far we expect ESOS to benefit British business by helping companies to reduce overheads and increase competitiveness.

The UK?s Energy Saving Opportunity Scheme ESOS is a gold mine of opportunities for big business, the environment and the population that breathes the air. Measurement of critical energy throughputs is the beginning of the process. EcoVaro is standing by to help you convert your data to meaningful information.

Spreadsheet Risk Issues

It is interesting to note that the riskiness of operational spreadsheets are overlooked even by companies with high standards of risk management. Only when errors amount to actual losses do they realize that these risks have been staring them in the face all along.

Common spreadsheet risk issues

Susceptibility to trivial manual errors

Due to the fundamental structure of spreadsheets, a slight change in the formula or value in any of their inhabited cells may already affect their overall output. An

  • accidental copy-paste,
  • omission of a negative sign,
  • erroneous range selection,
  • incorrect data input or
  • unintentional deletion of a character,cell, range, column, or row

are just some of the simple errors spreadsheet users frequently encounter. Rarely are there any counter-checking controls in place in a spreadsheet-based activity and manual errors therefore easily go undetected.

Possibility of the user working on the wrong version

How do you store spreadsheet files?

Since the most common reports are usually generated on a monthly basis, users tend to store them using variations of these two configurations:

spreadsheet storage

If you notice, a user can accidentally work on the wrong version with any of these structures.

Prone to inconsistent company-wide reporting

This happens when a summary or ?final? spreadsheet is fed information by different departments coming from their own spreadsheets. Even if most of the data in their spreadsheets come from one source (the company-wide database), erroneous copy-pasting and linking, or even different interpretations of the same data can result to contradicting information in the end.

Often defenceless against unauthorised access

Some spreadsheets contain information needed by various individuals or department units in an organisation. Hence, they are often shared via email or through shared folders in a network. Now, because spreadsheets don’t normally use any access control, any user can easily open a spreadsheet file and view or modify the contents as he wishes.

Highly vulnerable to fraud

A complex spreadsheet system with zero or very minimal controls provides the perfect setting for would-be fraudsters. Hidden cells with malicious formulas and links to bogus information can go unnoticed for a long time especially if the final figures don’t deviate much from expected values.

Spreadsheet risk mitigation solutions may not suffice

Inherent complexity makes testing and logic inspection very time consuming

Deep testing can uncover possible errors hidden in spreadsheet cells and consequently mitigate risks. But spreadsheets used to support financial reporting are normally large, complex, highly-personalised and, without ample supporting documentation, understandably hard to follow.

No clear ownership of risk management responsibilities

There?s always a dilemma when an organisation starts assigning risk management responsibilities for spreadsheets. IT personnel believe users in the business side of the organisation should be responsible since they are the ones who create, edit, store, duplicate, and share the spreadsheet files. On the other hand, users believe IT should be responsible since they have always been in-charge of managing IT infrastructure, applications, and files.

To get rid of spreadsheet risks, you’ll have to get rid of spreadsheets altogether

One remedy is to have a risk management activity that involves both IT personnel and spreadsheet users. But wouldn’t you want to get rid of the complexity of having to distribute the responsibilities between the two parties instead of just one?

Key Steps to Complying with ESOS

Energy Savings Opportunity Scheme has already been launched. In fact, it is by now in its initial phase. However, many businesses are still not aware of the new scheme, especially those who are covered by the qualifications for ESOS. To help them understand what they need to do in compliance to the energy efficiency strategy, here are key steps they can follow along the way.

Measure Overall Energy Consumption

The first step to complying with ESOS is to make an initial estimate of the business? energy consumption. This includes measuring the use of electricity, renewable energy, combustible fuels and all other forms of energy consumed whether in buildings, transports and industrial processes.

Three important factors to consider are the measurement units used, the reference period and quality of data. Energy units, such as MWh and GJ, or energy expenditure costs should be applied. Business enterprises should also do the initial measurement within a reference period of 12 months. Moreover, data collected should be verifiable at hand.

Identify Areas of Significant Energy Consumption

When the total energy consumption for all the activities and assets has already been estimated, it’s then time to identify what areas in the organisation comprise the significant portion of the overall energy usage. The areas recognised should cover at least 90% of the overall consumption. Meaning to say, ESOS participants have the chance to omit 10% of the energy consumption and instead focus on the 90%. This would ensure that subsequent energy audits will be cost-effective and proportionate.

Consider and Choose Compliance Routes

In order to comply with ESOS, qualified businesses should consider what compliance routes to take. These routes include taking series of energy audits, operating and implementing a certified ISO 50001 energy management system, acquiring Display Energy Certificates (DECs) and working with Green Deal assessments. Whichever route the business takes, one should maintain credible evidences, along with helpful documents, to certify their compliance.

Report the Compliance

Except when the large enterprise covers all the significant areas of energy consumption by means of ISO 50001 certification, one should appoint a lead assessor to supervise, conduct and review the organisation’s chosen ESOS compliance route. In this case, the approved assessments should then be signed off at board level to ensure that the conclusions and recommendations for energy savings are properly carried. To confirm their compliance, the business should submit a formal notification to the Environment Agency.

Because ESOS is not just an opportunity but also an obligation, it designated compliance bodies and gave them the authority to file civil penalties towards those who fail to comply with the scheme. Not only that, these appropriate authorities have the right to publish information about non-compliant enterprises including their name, details of non-compliance and corresponding penalty amount. Among these UK compliance bodies are Natural Resources Wales, Environment Agency in England, The Scottish Environment Protection Agency (SEPA) and Northern Ireland Environment Agency.

So, if you are covered with the ESOS qualifications, make sure to be informed. As the famous saying goes, ?Ignorance of the law excuses no one.? Likewise, awareness of ESOS is a responsibility every large business in UK should give importance to.
