Yesterday, I deposited a check from a client into our corporate checking account. Today, while at the bank to make another deposit, I inquired with the teller as to whether that check had cleared. She was unsure, so she referred to one of her colleagues to ask if the check had cleared because the funds were in my account. Continue reading “Don’t let anyone tell you “nobody knows.””
On March 27, I made an offer on a new condominium across town. It was priced just on the edge of what I could afford, but the location is great, and I really love the unit, so I decided to stretch myself a bit and make an offer. Across town, there was another very attractive condo with a lot of pluses going for it, and it was priced significantly lower. However, it was clearly my second choice.
I really wanted to hedge my bets by submitting offers on both units, just in case one would be rejected, because given how competitive the Boston housing market is, this was a high likelihood. However, since both sellers wanted offers to be submitted by Tuesday morning, I didn’t really have any wiggle room. Also, there was a chance that the offer on my second choice would be accepted before my first one, that I would have to accept their deal to lock it in, and then have my offer on my first choice to be accepted, causing me to lose my deposit or be stuck with my second choice. Not cool!
Rather than taking this risk, I decided to put my energy into my primary choice. I sharpened my pencil, calculated what I could afford, and made my offer, settling at 5% over asking price. Finally, I wrote a short letter of introduction. As I said to my real estate agent, it wasn’t my best work, but I hope to that it would make a difference. What I wrote is below:
Dear <Seller's Name>, I had the pleasure of visiting your condo yesterday during the open house, and I’m very interested in purchasing it. I love the layout and the location, and can easily see myself happily living there for some time – especially if I have a private space to do my morning yoga routine in that awesome third floor space! I understand you would need to find suitable housing before you could depart. To help you with this, you could continue to live there through July - which should give you ample time to find your new home – as long as my basic costs for the property (mortgage, taxes, insurance, and HOA fee) are covered. If there’s anything we can do to help come to a mutually-beneficial agreement, please let me know! Sincerely, Peter Nikolaidis
Since I had noticed that the seller practices yoga – as was evidenced by several yoga books throughout the condo, I decided to reference that, as I didn’t have much else by which to form a connection. Given how quickly the Boston real estate market moves, it’s not like I could say “let’s get together for coffee next week and go over what you want to get out of this transaction,” so I had to go with what little info I could gather. Also, since I the sale was contingent on the seller finding her own location, and I was not in a hurry to move, I decided to offer her an extended stay if she was not able to find housing prior to closing.
It worked! My agent called me in the afternoon to tell me that they had narrowed selection down to three offers, and that they wanted our “best and final.” This is a common tactic to squeeze a little more money out of the buyers, and why not? It works, doesn’t it? (Note, the last time I had bid on a condo, and was asked for my best and final, my response was “you already have it.”) I went back to the drawing board, sharpened my pencil… again, and offered $2,000 more. Several hours crawled by from that point. My agent called me back that evening to tell me that my offer had been accepted, even though someone else had offered $8,000 more than my final bid! I was told that the seller’s agent liked my agent the best, and that the seller really liked my letter of introduction.
The moral of the story is “pay attention, communicate clearly, use every resource at your disposal, and be nice to people.”
Today, after leaving a meeting, one of my junior analysts said “I guess we need to lower the threshold for declaring an incident.” Intrigued, I asked what brought him to that conclusion. He said “well, our incident response plan says that we organize the team if more than ten computers are affected, but you just said that an incident is any event that indicates harm or malice.” Realizing that further clarification was required, I resorted to my favorite tools: analogies and metaphors.
I gave the example of Captain America hearing a car alarm going off. This is just an event, and not yet an incident. Why? Surely if a car alarm is going off, something bad is happening, right? No, not necessarily. It could have been set off by the owner by accident, by a teenager zipping by on his skateboard and accidentally slamming into the car, or another car bumping into it while parking. While these are all (noteworthy?) events, none of them represent an incident in the security context because nothing really bad was happening, and there was no evil intent.
This is the equivalent of an analyst detecting an alert on the corporate SIEM. The analyst notes that there are a large number of failed logons occurring on a system. Investigating, he finds that they are all originating from a single workstation, which was unable to log on due to a recent password change. Is this an incident? No.
Taking it to the next phase, let’s say that Cap does investigate, and he sees that the alarm was set off not by some passing skateboarder, but by a common street thug. Does Cap yell “AVENGERS, ASSEMBLE!?” No, not yet. Some two-bit thug trying to jack a car is well within Captain America’s ability to cope with without needing to call upon other members; you don’t call for Thor and Iron Man just because you’ve got them on speed dial, and Cap knows that.
This could be likened to the analyst detecting malware on the affected system. Perhaps this malware was trying a brute force attack against a random system on the network. The analyst tasks the antivirus software to re-scan the system and do a cleanup, which it does successfully. Problem solved, with no need to bring on additional help.
Even if the guy breaking into the car turns out to be Batroc, Cap doesn’t go crying for help, because he can has handled the likes on his own many times in his extensive career. But what if Batroc is not alone, and is accompanied by his brigade of super villains? This is where it gets a bit subjective. Being a seasoned incident responder, Cap is likely to attempt an immediate intervention in their nefarious activities, even though he’s outnumbered. However, if he starts to realize he’s being overwhelmed, Captain America is not too proud to reach out to a nearby resource like Bucky, the Falcon, or Spider-Man if he’s nearby. Since he has an established relationship with many other super-powered resources around the world, help is just a quick call away.
The analyst continues to investigate, and finds that there is malware on the affected system, and also notices alert that other nearby systems are apparently infected with the same malware. Contacting the department IT liaison, he finds that they are aware of the infection, which was passed around by a shared USB drive. Working together, the department contact and the analyst are able to clean up the malware before it spreads beyond the handful of machines.
But, let’s say that Cap notices it’s not just an ordinary thug, and not even just Batroc’s Brigade, but it turns out that, for some reason – don’t ask why – it’s Ultron who has decided to steal this car. As a villain who has tried to destroy the world, and come awfully close to doing so, this is immediately dubbed a very serious incident.
Further investigation reveals that multiple systems have been infected, and are communicating to an external IP address in a remote location. There is now evidence that classified data is being exfiltrated from the network. It’s time to call on extra help. The incident response team, consiting of members of the networking, server administration, and department IT teams, are notified, and a command center is established. The team immediately begins to compare notes to determine what is going on, and how to contain the threat.
This is why Captain America’s got not just Bruce Banner’s cell phone, Nick Fury’s SUV phone, and Tony Stark’s office number, but also Pepper Potts’ pager (because she’ll be able to get a hold of Tony, regardless of what lady has caught his attention this evening). Cap also has a plan, which directs him to notify the regular members of the team.
This is why the incident response plan must be regularly updated to include a current list of contacts, the systems for which they are responsible, and their best contact methods.
If it turns out that things are getting really bad, he may need to call upon a specialist. For example, since Ultron is (these days, anyway) made largely of vibranium, it may make sense to call upon someone with extensive knowledge of the precious metal – good thing Cap kept T’Challa’s Whatsapp handle at the top of his favorites! Now the Black Panther is only a hop, skip, and a jump away from joining the team. If other threats are encountered along the way, say, it’s found that Doctor Doom may be collaborating with Ultron, more help – in the form of the Fantastic Four – may be called upon, as they have extensive experience dealing with Victor von Doom, and can likely help contain the threat in a timely fashion.
The organization maintains relationships with law enforcement, their ISP, and outside security firms who can supplement the incident response team if required. Calling on a professional services firm to assist with containing an advanced persistent threat may be called for, as well as notifying law enforcement or various government agencies, depending on the nature and scope of the breach that has occurred.
Is every day in the life of a security analyst as exciting as that of an Avenger? Probably not. But it can be fun, at times, especially if you like being a hero. If you think you have relevant skills or information that could be useful in a security incident, let your local security team know, and ask how you could be of help during a crisis. Who knows? You may just get a snazzy, new ID card to carry around.
In late June, I made some measured modifications to my now-(depending on how you define it) famous slow carb diet practice.
For starters, I resumed drinking Gatorade during Krav Maga training sessions. I noticed an immediate increase in my mental acuity and energy levels, resulting in better training, both physically and mentally. I am also allowing myself up to one soda – usually club soda, lemon juice, and stevia – per day.
Next, I allowed myself one “slip day” (in addition to my cheat day) per week, where I can eat restricted foods (dairy, or grains) provided I do so after a resistance training workout, and I stay within my daily total energy expenditure (so if I have a couple slices of pizza after hitting the gym, and keep the calories sane, I’m okay.
I’m also skipping breakfast – yes, the most important meal of the day – on most days. Also, I haven’t been eating as many legumes as previously, usually only having them a few days or of the week now.
Finally, I allow myself some night time carbs. This has usually been a small amount of dark chocolate, but could also be a granola bar. In addition to satisfying any cravings, this had resulted in better quality sleep than melatonin, valerian, or GABA. Again, I make sure to stay within my daily TEE so this is not a bingefest like some Saturdays turn into.
The results? Not much to report, actually. There has been a modest decrease in weight over the last few weeks, but nothing dramatic.
Given all of these adjustments, I’m not sure it even qualifies as the slow carb diet even more, but hey! As long as it works, I’m happy.
