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.

Systems Integration as a means to cost reduction

System integration in an organisation refers to a process whereby two or more separate systems are brought together for the purpose of pooling the value in the separate systems into one main system. A key component of process consolidation within any organisation is the utilisation of IT as a means to achieve this end. As such, system integration as a means to cost reduction offers organisations the opportunity to adopt and implement lean principles with the attendant benefits. The implementation of lean techniques requires an adherence to stated methods to facilitate the elimination of wastage in the production of goods and services. In summary, the lean philosophy seeks to optimise the speed of good and service production, through the elimination of waste.

While analysing some of the traditional sources of waste in organisational activities, things like overproduction, inventory, underutilised ideas, transmission of information and ideas, transportation of people and material, time wastage and over-processing stand out. The fact is that companies can eliminate a significant portion of waste through the utilisation of IT to consolidate processes within their organisation.

Adopting lean principles calls for the identification of all of the steps in the company value stream for each product family for the purpose of the eliminating the steps that do not create any value. In other words, this step calls for the elimination of redundant steps in the process flow. This is exactly what the utilisation of IT to consolidate processes offers a company. For instance, the adoption of a central cloud system across a large organisation with several facilities could increase efficiencies in that company. Such a company would drastically reduce the redundancies that used to exist in the different facilities, eliminate the instances of hardware and software purchase, maintenance and upgrade, modernise quality assurances processes and identify further opportunities for improvement.

Perhaps, from the company’s point of view, and from the perspective of lean process implementation, the most important factor is?the effect it has?on the bottom line.’reducing the number of hardware, eliminating the need for maintaining and upgrading hardware, removing the necessity for software purchase and upgrade across facilities also contributes to a significant reduction in operational costs.?This reduction in the cost of operations leads to a corresponding increase in the profit margin of the company.

Applying system integration as a means to cost reduction can also lead to the reduction in the number of people needed to operate the previous systems that have been integrated into one primary unit. Usually, companies must hire people with specialised knowledge to operate and maintain the various systems. Such employees must also receive special training and frequent ongoing education to constantly stay informed of the latest trends in process management. With the integration of the system, the number of people needed to maintain the central system will be significantly reduced, also improving the security of information and other company trade secrets.

Based on an analysis of the specific needs that exist in a particular company environment, a system integration method that is peculiar to the needs of that organisation will be worked out. Some companies may find it more cost-effective to use the services of independent cloud service providers. Others with more resources and facilities may decide to set up their own cloud service systems. Often, private cloud service system capabilities far exceed the requirements of the initiating company, meaning that they could decide to “sell” the extra “space” on their cloud network to other interested parties.

A company that fully applies the lean principles towards the integration of its systems will be able to take on additional tasks as a result of the system consolidation. This leads to an increase in performance, and more efficiency due to the seamless syncing of information in a timely and uniform manner.

Companies have to combine a top-down and a bottom-up approach towards their system integration methods. A top-down approach simply utilises the overall system structure that is already in place as a starting point, or as a foundation. The bottom-up approach seeks to design new systems for integration into the system. Other methods of system integration include the vertical, star and horizontal integration methods. In the horizontal method, a specified subsystem is used as an interface for communication between other subsystems. For the star system integration method, the subsystems are connected to the system in a manner that resembles the depiction of a star; hence, the name. Vertical integration refers to the method of the integration of subsystems based on an analysis of their functionality.

The key to successful system integration for the purpose of cost reduction is to take a manual approach towards identifying the various applicable lean principles, with respect to the system integration process. For instance, when value has been specified, it becomes easier to identify value streams. The other process of removing unnecessary or redundant steps will be easier to follow when the whole project is viewed from the whole, rather than’the part. Creating an integrated system needs some?patience?in order to work out kinks and achieve the desired perfect value that creates no waste.

2015 ESOS Guidelines Chapter 7, 8 & 9 – Sign-Off, Compliance & Appeals

This is the final chapter in our series of short posts summarising the quite complex ESOS guidelines (click on ?Comply with ESOS? to see the details). This one addresses the legalities to follow to complete your report – and how to appeal if you are not happy with any of the Environment Agency?s decisions.

  1. Director Sign-Off

This is by no means an easy ride. Confirmation of the work at individual or lead assessor level locks the company into the penalty cycle in the event there are significant irregularities. By signing off the assessment, the board level director(s) # agree that they have

  • Reviewed the enterprise?s ESOS recommendations
  • Believe the enterprise is within the scope of the scheme
  • Believe the enterprise is compliant with the scheme
  • Believe the information provided is correct

Having an internal assessor requires a second board-level signature.

  1. Compliance

You report compliance on the internet. This is free and you can do it at any time within the deadline. You can dip in and out of the process as many times as you wish, but must use the link in the receipting email. While this is something a board member must do, there is no reason why the lead assessor should not complete the basics. The online compliance notification addresses the following topics:

  • The ESOS contact person in the enterprise
  • Any aggregation / dis-aggregation during the period
  • The names and contact details of the lead assessor
  • The proportion of energy consumption per compliance route

The Environment Agency will acknowledge receipt. This does not constitute acceptance. You should keep the ESOS evidence pack in a safe place with at least one backup elsewhere.

  1. Compliance & Enforcement Issues

In the event the Environment Agency decides your enterprise has not met ESOS requirements, it may either (a) issue a compliance notice with instructions, or (b) apply one of the following civil penalties:

  • A fine of up to ?5,000 for failure to maintain records
  • A fine of up to ?50,000 for failure to undertake an energy audit
  • A fine of up to ?50,000 for a false or misleading statement

Any enterprise has the right of appeal against government decisions. In the case of ESOS, this is via:

  • The First-Tier Tribunal if your enterprise is England, Wales or off-shore based
  • The Scottish Minister if your enterprise is based in Scotland
  • The Planning Commission if your enterprise is Northern Ireland-based

The notice you appeal against will supply details of the appeal steps to take.

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.
