surely_you_cant_be_serious writes "A nationwide survey finds that most companies consider their systems vulnerable to attack. Historically, crime rates increase during recessions — and some believe that cybercrime may well follow suit, especially given massive layoffs and the dim prospects many laid-off employees face in finding a new job. 'One thing companies can start doing is monitoring their networks on an ongoing basis so that they understand the normal pattern of data flow and usage, Brill said. In many cases, companies may not have the internal capability to do this, but outsourcing options are available. Kroll Ontrack, for instance, will be rolling out a 24/7 monitoring service for its global clients manned from a US location by professionals in early 2009.'"

The Year of 2008 In Cybercrime 47 comments
BobB-nw writes "Underground botnet markets and high-profile spam cases headlined the year in tech crime. One of the most disturbing cybercrime trends in 2008, many security analysts say, has been the emergence of a full-blown underground economy where credit card information, identity theft information, and spam and phishing software are all available for relatively low prices. 2008 also saw major developments in the cases against three major spammers in the United States."

Summary of story:
1.) Crime goes up when the economy goes into the tank and people start losing their jobs. Shocking, I know.
2.) There are plenty of security companies willing to scare your pants off in order to sell you expensive monitoring services. They will gladly use the statistic above to those ends.
Oh yah, and we'll throw a "cyber" prefix in front of "crime" to make this look like something new and different.

Exactly. It makes sense that crime by unemployed people goes up in a recession. But the main risk in a company's systems being hacked by insiders. If you have an effective termination process, which includes revoking access, laid off ex-employees are no longer insiders.
However, I'm sure this kind of service is important for some companies, such as Kroll Ontrack, to survive the recession.

Well... revoking access is hypothetically a no-brainer. ("Hypothetically" because it's still shockingly uncommon.)
But a former insider may still know enough about your environment to make an extremely effective blackhat. Not much you can do about that without using a big hammer, a la Catbert, to remove your employee's detailed knowledge before escorting him/her out.
Re:Duh? (Score:5, Insightful)
In a recession, somebody employed yet still enduring paycuts would probably be somewhat disgruntled too, even if not "terminated" per se (but with terminations all around said employee, or the looming fear of termination imminent). An employee with access to something worth anything would still be able to take it and run, and the possibility of him/her doing so in a recesssion/depression with constant paycuts and the constant threat of layoff is rather high, so this is where it gets hairy - how much do you trust your fellow employees? You can't cut present employees' access!
Well, now that I've struck fear into the heart of any employers/administrators reading this, I don't think this recession is quite to that point yet, but it may be something to watch down the road if things keep getting progressively worse.

Employees who feel their jobs becoming less secure may decide to take out an insurance policy while they still have access to the important data.
Regardless of how you treat your employees, regardless of how secure their jobs are, in a crappy economy they may feel that their jobs are insecure, and that may lead them to the dark side.
Having good security standards and processes will lessen your exposure. Maintaining employee morale will lessen your exposure. In the end, though, as long as one person has access to critical data, there is risk of the data being misused.

That might be true, but regardless it has always been true that employees have been one of the big security risks for businesses. In one way of dividing things up, security basically falls into two categories: denying access to people who shouldn't have access and preventing those who have access from abusing their access.
Think about a bank, for example. Protecting against bank robberies is one kind of security problem, but it's not really the hardest thing to do. You put things in a vault, lock the vault, install an alarm, hire security guards, etc. The trickier issue is that you have all these employees with access to the money, and if there are no security measures, it wouldn't be hard for a teller to pocket a hundred dollars every now and then. So banks have procedures where the tellers have to do account for the money in their drawers at the end of the day (or whatever the particular procedure is).
So computer security isn't really much different. Instead of vaults and locks and security guards, we have encryption and firewalls and antiviruses. Protecting against external threats isn't really that hard a lot of the time. Most of the time, the biggest dangers are either directly or indirectly from employees. It's a very tricky security issue to deal with, since you can't "plug the hole"-- employees are *supposed* to have access.
And when I talk about dangers that come "indirectly from employees", I mean that they might be the source of a breach even if they aren't themselves criminal or dishonest. I've heard hackers say that often social engineering (i.e. getting an authorized employee to give you access) is easier than actually exploiting any security holes.
Besides the danger of purposeful social engineering attacks, employee carelessness can also leave you exposed. People often choose bad passwords in spite of good password policies, i.e. just because you make them use a 10 character combination of letters/numbers/symbols doesn't mean they won't choose a password that's easy to guess (Passw0rd!!). Also people do things like access a secure webpage in an Internet cafe computer (which might have keyloggers installed for all anyone knows) and then walk out without closing or logging out, or put highly sensitive data on a usb stick and lose it somewhere. Sometimes employees even go through a lot of trouble to pierce their company's security (for example, in order to get Kazaa working inside the firewall) and effectively open a hole to potential hackers, too.
So overall, yes, employees are a big potential danger to securing your data. A criminally inclined employee can cause lots of damage, but so can a careless one.

Companies could go a long way in avoiding this kind of behavior if they didn't fall for the false dichotomy of "Access to everything" and "Work is supposed to suck". I know you didn't say it, but these kinds of articles always bring out the admins that recommend that every machine should be locked down to the point of basically being a kiosk often actually preventing people from doing their job, and rationalize that since "it's the companies" computer, it cannot be used to make work a place people want to go.
This always gives me images of the bad boss from 9 to 5. After all, how much different is it for a real live admin to tell an office worker that they can't have a picture of their family on their desktop than the fictional manager who told the characters in the movie that they cannot have pictures of their family on their... desktop?
Businesses regularly spend money to try to make their business a 'good place to work'. There is a huge amount of safe area between "full access to anything" and "treat it like a bank vault". The PC is one of the least expensive ways to improve a work environment. A $2 set of headphones, or even just making sure that the CD drive can play music and let the employee bring their own headphones goes a long way to improving a work environment. Heck, have the admins 'certify' a safe CD ripping app, and you are less likely to have people downloading random rippers from who knows where.
Most people are going to respect "Music must be ripped using THIS easy to use software so that we can secure against viruses." a lot more than "Music is not allowed in our company". If you take the later route, you have a much higher risk of employees just ignoring the rules and going with Kazaa. Heck, the people that feel they MUST get music from Kazaa will still be safer in that they are more likely to do the downloading from home, and sanitize the files by first converting them to standard CD format, before bringing them to work and re-ripping them.
Instead of trying to prevent employees from accessing the internet, give them access to virtual machines that have no access to the company network. This makes the path of least resistance be not being a security risk, instead of encouraging people to try and circumvent the companies security AND making work a crappy place to be.

Evil Bad Hacker comes in and drops a trojan on one of those systems. A few days later, Evil Bad Hacker does a SELECT * FROM... fill in the blank... and in a few minutes it's compressed and uploaded. Super Important Data Stuffs was only 2 GB in size. How does your solution, or any solution, stop this while it's happening? Short answer: It doesn't.

Seriously. Ok, employees are obviously a potential security risk, they are the ones who have legitimate access to the gates and the keys, of course there is a risk. And, in some cases, you'll get genuinely bad apples, sociopaths, paranoics with bizarre persecution complexes, fred in accounting with the gambling problem, etc. In most cases, though, you are basically just dealing with people. And people will be a lot happier, more productive, and less dangerous if you spend less money on orwellian surveillance consultants and more on them. Does anybody seriously think that an office full of bitter, resentful employees, even under the all-seeing-eye of your consultants is less of a security risk than an office full of more or less satisfied people, with standard, basic, procedures in place(particularly given that, in a lot of cases, somebody with basically no assets can do damage that cannot be repaired and costs more than they could ever repay, even if the lawsuit goes well)?
A back-to-front mentality (Score:5, Insightful)
(1) view employees purely as resources (about on level with the printers and the staples)
(2) use every possible means to make their job manageable for the Human Resources department (which is shorthand "define all tasks in such a way that every individual instantly plug-replaceable by (a) your average worker in the job market with his job title and (b) any of his colleagues, actively remove any individuality, and rather waste someone's talents than allow him to enrich his job")
(3) use HRM to "Dynamically contribute to optimization of enterprise processes and results" (translation: hire people when they are marginally qualified for their job and let their colleagues educate them, fire 'em the instant they become overqualified and aren't immediately placeable in a higher function, or if they show signs of become tired, bored, jaded, cynical, or if they catch on to what Human Resource Management really means for them)
(4) use an elaborate system of "who reports to whom", physical access checks and "security" guards, to ensure that people are total strangers in the company they work for with the sole exception of the department they work (this enhances "security")
(5) determine scientifically that your employees may spontaneously become disgruntled and hostile towards the company they work for (or after being fired)
(6) determine that the company urgently needs to protect itself from the consequences of its employees becoming disgruntled and hostile
(7) further plan employees jobs and tighten "security" so that the amount of damage any disgruntled individual below the rank of executive can do is reduced to an acceptable minimum.
The final step (8) is to spend good money to outsource security and workflow monitoring to establish tight restrictions on what employees can mess up before being physically apprehended. Outside firms have nice glossy brochures that provide your board with plenty of reasons why employees should be treated as detainees rather than as collaborators. Recommending specialized outside firms to cover specific areas of employee containment definitively establishes you as a savvy and professional manager (and keeps you in line for that end-year performance bonus).
On the other hand, the suggestion of actually treating employees as if they were collaborators confuses simple PR slogans meant for glossy company brochures with actual management. Expecting people to behave civilly when treated like people is naive in the extreme and something no manager with an ounce of professionalism should sully himself with.
Recognize this mindset? I foresee that work-flow monitoring will become a growth industry.

When I worked for a law firm, there was a department called Litigation Support that changed its name to Technology Services and competed with Information Systems.

Black Ice traced the attacks to Technology Services PC systems. When I reported the fact to my boss, he told me to take Black Ice off my system. Then it started crashing again. Eventually it stopped, but I had missed a few deadlines because my computer would crash or freeze up or lose the network connection, and it wasted my time trying to develop programs. Later on I got a bad performance review, but my boss refused to listen to me about hacker type attacks from TS directed at my IP address, despite the proof I had from Black Ice logs.
