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:

New Focus on Monitoring Soil

There is nothing new about monitoring soil in arid conditions. South Africa and Israel have been doing it for decades. However climate change has increased its urgency as the world comes to terms with pressure on the food chain. Denizon decided to explore trends at the macro first world level and the micro third world one.

In America, the Coordinated National Soil Moisture Network is going ahead with plans to create a database of federal and state monitoring networks and numerical modelling techniques, with an eye on soil-moisture database integration. This is a component of the National Drought Resilience Partnership that slots into Barrack Obama?s Climate Action Plan.

This far-reaching program reaches into every corner of American life to address the twin scourges of droughts and inundation, and the agency director has called it ?probably ?… one of the most innovative inter-agency tools on the planet?. The pilot project involving remote moisture sensing and satellite observation targets Oklahoma, North Texas and surrounding areas.

Africa has similar needs but lacks America?s financial muscle. Princeton University ecohydrologist Kelly Caylor is bridging the gap in Kenya and Zambia by using cell phone technology to transmit ecodata collected by low-cost ?pulsepods?.

He deploys the pods about the size of smoke alarms to measure plants and their environment.?Aspects include soil moisture to estimate how much water they are using, and sunlight to approximate the rate of photosynthesis. Each pod holds seven to eight sensors, can operate on or above the ground, and transmits the data via sms.

While the system is working well at academic level, there is more to do before the information is useful to subsistence rural farmers living from hand to mouth. The raw data stream requires interpretation and the analysis must come through trusted channels most likely to be the government and tribal chiefs. Kelly Caylor cites the example of a sick child. The temperature reading has no use until a trusted source interprets it.

He has a vision of climate-smart agriculture where tradition gives way to global warming. He involves local farmers in his research by enrolling them when he places pods, and asking them to sms weekly weather reports to him that he correlates with the sensor data. As trust builds, he hopes to help them choose more climate-friendly crops and learn how to reallocate labour as seasons change.

Migrating from CRM to Big Data

Big data moved to centre stage from being just another fad, and is being punted as the latest cure-all for information woes. It may well be, although like all transitions there are pitfalls. Denizon decided to highlight the major ones in the hope of fostering better understanding of what is involved.

Accurate data and interpretation of it have become increasingly critical. Ideas Laboratory reports that 84% of managers regard understanding their clients and predicting market trends essential, with accelerating demand for data savvy people the inevitable result. However Inc 5000 thinks many of them may have little idea of where to start. We should apply the lessons learned from when we implemented CRM because the dynamics are similar.

Be More Results Oriented

Denizon believes the key is focusing on the results we expect from Big Data first. Only then is it appropriate to apply our minds to the technology. By working the other way round we may end up with less than optimum solutions. We should understand the differences between options before committing to a choice, because it is expensive to switch software platforms in midstream. data lakes, hadoop, nosql, and graph databases all have their places, provided the solution you buy is scalable.

Clean Up Data First

The golden rule is not to automate anything before you understand it. Know the origin of your data, and if this is not reliable clean it up before you automate it. Big Data projects fail when executives become so enthused by results that they forget to ask themselves, ?Does this make sense in terms of what I expected??

Beware First Impressions

Big Data is just that. Many bits of information aggregated into averages and summaries. It does not make recommendations. It only prompts questions and what-if?s. Overlooking the need for the analytics that must follow can have you blindly relying on algorithms while setting your business sense aside.

Hire the Best Brains

Big Data?s competitive advantage depends on what human minds make with the processed information it spits out. This means tracing and affording creative talent able to make the shift from reactive analytics to proactive interaction with the data, and the customer decisions behind it.

If this provides a d?j? vu moment then you are not alone. Every iteration of the software revolution has seen vendors selling while the fish were running, and buyers clamouring for the opportunity. Decide what you want out first, use clean data, beware first impressions and get your analytics right. Then you are on the way to migrating successfully from CRM to Big Data.

How to Reduce Costs when Complying with SOX 404

Section 404 contains the most onerous and most costly requirements you’ll ever encounter in the Sarbanes-Oxley Act (SOX). In this article, we?ll take a closer look at the salient points of this contentious piece of legislation as it relates to IT. We?ll also explain why companies are encountering difficulties in complying with it.

Then as soon as we’ve tackled the main issues of this section and identify the pitfalls of compliance, we can then proceed with a discussion of what successful CIOs have done to eliminate those difficulties and consequently bring down their organisation’s IT compliance costs. From this post, you can glean insights that can help you plan a cost-effective way of achieving IT compliance with SOX.

SOX 404 in a nutshell

Section 404 of the Sarbanes-Oxley Act, entitled Management Assessment of Internal Controls, requires public companies covered by the Act to submit an annual report featuring an assessment of their company?s internal controls.

This ?internal control report? should state management’s responsibility in establishing/maintaining an adequate structure and a set of procedures for internal control over your company?s financial reporting processes. It should also contain an assessment of the effectiveness of those controls as of the end of your most recent fiscal year.

Because SOX also requires the public accounting firm that conducts your audit reports to attest to and report on your assessments, you can’t just make baseless claims regarding the effectiveness of your internal controls. As a matter of fact, you are mandated by both SEC and PCAOB to follow widely accepted control frameworks like COSO and COBIT. This framework will serve as a uniform guide for the internal controls you set up, the assessments you arrive at, and the attestation your external auditor reports on.

Why compliance of Section 404 is costly

Regardless which of the widely acceptable control frameworks you end up using, you will always be asked to document and test your controls. These activities can consume a considerable amount of man-hours and bring about additional expenses. Even the mere act of studying the control framework and figuring out how to align your current practices with it can be very tricky and can consume precious time; time that can be used for more productive endeavours.

Of course, there are exceptions. An organisation with highly centralised operations can experience relative ease and low costs while implementing SOX 404. But if your organisation follows a largely decentralised operation model, e.g. if you still make extensive use of spreadsheets in all your offices, then you’ll surely encounter many obstacles.

According to one survey conducted by FEI (Financial Executives International), an organisation that carried out a series of SOX-compliance-related surveys since the first year of SOX adoption, respondents with centralised operations enjoyed lower costs of compliance compared to those with decentralised operations. For example, in 2007, those with decentralised operations spent 30.1 % more for compliance than those with centralised operations.

The main reason for this disparity lies in the disorganised and complicated nature of spreadsheet systems.

Read why spreadsheets post a burden when complying with SOX and other regulations.

Unfortunately, a large number of companies still rely heavily on spreadsheets. Even those with expensive BI (Business Intelligence) systems still use spreadsheets as an ad-hoc tool for data processing and reporting.

Because compliance with Section 404 involves a significant amount of fixed costs, smaller companies tend to feel the impact more. This has been highlighted in the ?Final Report of the Advisory Committee on Smaller Public Companies? published on April 23, 2006. In that report, which can be downloaded from the official website of the US Securities and Exchange Commission, it was shown that:

  • Companies with over $5 Billion revenues spent only about 0.06% of revenues on Section 404 implementation
  • Companies with revenues between $1B – $4.9B spent about 0.16%
  • Companies with revenues between $500M – $999M spent about 0.27%
  • Companies with revenues between $100M – $499M spent about 0.53%
  • Companies with revenues less than $100M spent a whopping 2.55% on Section 404

Therefore, not only can you discern a relationship between the size of a company and the amount that the company ends up spending for SOX 404 relative to its revenues, but you can also clearly see that the unfavourable impact of Section 404 spending is considerably more pronounced in the smallest companies. Hence, the smaller the company is, the more crucial it is for that company to find ways that can bring down the costs of Section 404 implementation.

How to alleviate costs of section 404

If you recall the FEI survey mentioned earlier, it was shown that organisations with decentralised operations usually ended up spending more for SOX 404 implementation than those that had a more centralized model. Then in the ?Final Report of the Advisory Committee on Smaller Public Companies?, it was also shown that public companies with the smallest revenues suffered a similar fate.

Can we draw a line connecting those two? Does it simply mean that large spending on SOX affects two sets of companies, i.e., those that have decentralised operations and those that are small? Or can there be an even deeper implication? Might it not be possible that these two sets are actually one and the same?

From our experience, small companies are less inclined to spend on server based solutions compared to the big ones. As a result, it is within this group of small companies where you can find a proliferation of spreadsheet systems. In other words, small companies are more likely to follow a decentralised model. Spreadsheets were not designed to implement strict control features, so if you want to apply a control framework on a spreadsheet-based system, it won’t be easy.

For example, how are you going to conduct testing on every single spreadsheet cell that plays a role in financial reporting when the spreadsheets involved in the financial reporting process are distributed across different workstations in different offices in an organisation with a countrywide operation?

It’s really not a trivial problem.

Based on the FEI survey however, the big companies have already found a solution – employing a server-based system.

Typical server based systems, which of course espouse a centralised model, already come with built-in controls. If you need to modify or add more controls, then you can do so with relative ease because practically everything you need to do can be carried out in just one place.

For instance, if you need to implement high availability or perform backups, you can easily apply redundancy in a cost-effective way – e.g. through virtualisation – if you already have a server-based system. Aside from cost-savings in SOX 404 implementation, server-based systems also offer a host of other benefits. Click that link to learn more.
