Too many staff have privileged work accounts for no good reason, reckon IT bods

mmccul

You've reminded me of a former boss I had when I was a day to day sysadmin.

Near direct quote from said manager of sysadmins:

"If you give me an account on the servers, you get written up. If you give me root to the servers, you're fired."

The manager pointed out, they were the manager, not the sysadmin. They also didn't have the training to be safe as a sysadmin. One of the two best managers I've ever had.

Re: Employ people you trust, trust people you employ

My experience with git repos is that there is a culture in many developers of "give the world access", even to those individuals who have no legitimate reason to access the repo in question. It's a battle I'm currently fighting, that I do not need access to the git repos. My boss agrees with me. But devs repeatedly try and give me access in an effort to make me do their job for them. All because I "might need" access to the repo.

Re: .. all the access they ask for ..

I've been the person who had to explain that no, we are not going to authorize `sudo vi /etc/hosts` for a dev on production or QA (not a made up example) because that gives unrestricted root. You are absolutely correct that many times, the requester does not understand the implications of what they are asking for.

On the other hand, I've also been the person filing an access request. At one client recently, I was appointed the unofficial access requester, because mysteriously, my access requests were always approved. Maybe it was the fact that I spelled out explicitly what the business justification was, and crafted the access request to be the minimum necessary to meet that business justification. It added value to the client, and made them happy, so I was happy to take home the paycheck...

Re: risks been shown with electronic and mass postal voting

Regarding reliable voting, the problem I've seen is not the precinct, but the tallying of multiple precincts for the official reporting of the county results. A little county in Wisconsin had their elected official refuse to allow their Internet connected computer that did all that work to be patched, maintained, or even audited by a 3PAO. (Resulted in a bit of a scandal a decade ago, the individual was an elected official, so couldn't be fired as a result, and argued as an elected official, they were exempt from policies to maintain the security of computers issues by others).

Take all those per precinct numbers, add them up on one little computer, that just quietly rewrites the final results to the desired number. Tallying any individual machine won't reveal any problem, or any significant percentage of votes. Only when you look at the whole county level can you see that something messed up happened, and it only requires attacking one computer and skewing a few percentage points the final sums.

Re: Loss of human contact

Interestingly, I worked on a fully remote team for many years, ending just under a decade ago. Never met any of my peers face to face I worked with for a full fifteen years. Most of the teams in the division (several hundred people) were similar, no more than a couple people per roughly ten person team in the same city, and significant percentages of people working full time remote from home.

The key difference was the recognition among the team that the workplace was not our personal life. I had a more active social life then than I've had ever since. I think those that desire more social interaction will find ways to do so.

As to loyalty? I believe that loyalty comes from how you are treated. When I've had a good manager who treated me well, I've felt more loyal. When I was treated as a replaceable machine cog, I didn't feel overly loyal to the company.

I cannot speak conclusively to your statements on productivity, but even the connectivity of twenty years ago is a radically different situation than the 1960s office. I question if those results are still relevant to the physical office today, or if they instead suggest that smaller focused subteams may be more productive today.

How many mishandled medical records?

I seem to recall potential criminal liabilities for the mishandling of PHI data written into HIPAA from the training I get evey six months at any company that potentially handles PHI. Yes, there are a few oddities and special cases related to reporting data about COVID more precisely than HIPAA normally allows, but I seriously doubt that the college is exempt from the rules requiring strict proper handling and penalties for mishandling and failure to report such mishandling.

Re: Let's make it hypothetical:

You forgot the other item which really firmed up my views. When you have a clearance in the US, if you see something non-public but problematic, or potentially illegal, there is a whole process of "here is how to report it outside the chain of command". That method gets taught as part of the background/introductory training often before the clearance is even issued. From everything I've read, it wasn't even attempted. That lack of attempt at good faith whistleblowing suggests malicious motive.

In another area as an analogy, if someone sees a security vulnerability in a product that stores medical and financial information and reports it discretely, through the company's hackerone account or their security vulnerability reporting system, that's generally seen as a good thing. But, if said individual instead takes that same vulnerability and tells the world and the company about it by dumping personal medical and financial data for the world to see, unredacted, would that individual be celebrated? I would hope not, even if it also exposed illegal practices by the company.

Where to get competent staff?

Since I'm interviewing candidates very regularly for a variety of different infosec roles as a part of my job, I've found that one reason for burnout is the difficulty in finding competent staff. My employer has no incentive to fail to find good candidates, but so few of the candidates sent my way am I able to give a thumbs up for more than a tier-1 secops team staff -- the kind that does nothing but pre-written instructions developed by someone else.

I've seen roles go unfilled for a year or longer just trying to find a competent low to mid level security analyst. Add in any middle to high level skill and expect more of a senior technical security role, and the time can increase even more.

Easier to burn out when people leave and are not replaced, not because management won't let them be replaced, but because no one can find anyone they feel has the skills to be worth the cost of the chair they sit in.

Re: Audio rules ...

This may sound odd, but I don't want to know what they look like. Not knowing a person's appearance can reduce the risk of accidental unprofessional preconceptions. I don't even post a photo of myself on Teams or similar tools, just an avatar that does not show in any way what I look like. The only time a client objected, I removed all avatars and left it with just the default initials logo.

Re: Keep my Camera on?

Have regular meetings with people in different orgs. The security team members never turn on their cameras. The PMs usually do, until they realize that the security team people on the call won't be silently shamed into turning their camera on, and then the cameras turn off (and performance improves dramatically).

Amazon declined to sell a book so Elon Musk called for it to be broken up

Look into the then equivalent publications. Privately published pamphlets and broadsheets handed out on street corners that contained outlandish accusations against political or social enemies. The only real differences are first, cost of publication has gone down for these people. It used to be a moderate expense to reach a few thousand people in a city. Now, that's a lot cheaper. Second, speed is the other difference. It can take minutes for (mis)information to spread across the country rather than days or weeks.

For fun and education, I've read some of the late 1700s pamphlets. It is quite arguable that they played a significant role in the US Revolutionary war, drumming up support, demonizing those who were seen as sympathizing with the UK. I've seen similar pamphlets advertising quack miracle cures for diseases, attacking political straw men, etc.

Black Helicopters

When I self published a couple fiction novels on Amazon, Amazon had some criteria that I was warned about that could get my book removed. I recall seeing a link to the criteria, but since my next book is nowhere near ready to publish, I'm too lazy to go back and pull it up. As a commercial entity instead of a government, unless the reason falls into a legally protected category, Amazon is free to refuse to do business with someone, and it is merely courtesy to advertise in advance the reasons for such.

As an author, one is not a consumer but a content creator entering into a contract with a distributor. That is a very different situation. There are plenty of other distribution channels one could use and Amazon does not block them even on the Kindle devices.

Re: "No it won't"

HTTPS does not encrypt the SNI at this time, so a network snoop will still know where you are going.

Stop pushing DNS over HTTPS (a privacy nightmare as others have pointed out) and realize it is actually the worst designed of the options. Literally, DoH results in lower privacy than no encryption at all, because a third party that would never have seen who you are visiting now gets that information in a nice pat log. As I keep reminding people, your ISP knows where you go just from the network traffic -- if they care so much. With that and SNI, they don't need your DNS except for pushing ads.

Re: "Details" are irrelevant

They don't need to steal data to monetize this. They've built a way of recording who spends time at a booth or in a particular section of a store. Then they can send those people targeted advertisements, "oh, we don't actually record this location data, your phone just calculated that it was near this advert system, and thus pulled the relevant advertisements".

Re: spare disk space

When I learned manuscript format for submitting writing material for possible publication, I found it interesting that the explicit format was "Times New Roman, 12 point font, double spaced, one inch margins on all sides, two spaces after sentences," and failure to follow that format would result in your submission being tossed unread by many journals. Yes, some journals were different, but that was the most common standard, and it wasn't just what the instructor taught, it was demonstrated by the specified submission guide for the various places I looked at. I would not say it is just "because the teachers were taught that."

Word was, and remains, a typographic neophyte. Word uses the same sized space between words as it does between sentences based on my testing in the common fonts (e.g. Arial, Times New Roman, Verdana, Calibri).

Anti-privacy under privacy name

DNS over HTTPS is a privacy nightmare. Now, one place will see all your DNS queries, even if not intended for them. As many have pointed out, your ISP already knows where you are going just by looking at the IP headers and the unencrypted part of https requests your browser sends that includes little things like the domain name you are requesting (SNI).

I've noticed a lot of anti-privacy initiatives, like DNS over HTTPS, advertised in the name of "enhancing privacy" when really, it's just about encouraging people to log all their activity at yet another data aggregator that isn't normally in a position to capture any of the traffic at all.

The real question is not the confidentiality of DNS requests, but confidentiality of where you go. But the ISP, to route your traffic, has to know where you are going. Until https is rewritten, they always know the domain name you are requesting, even without looking at DNS queries. This is a solution in search of a problem, and considering who has been advocating it (various organizations that often make money by such), I am not convinced their motives are altruistic.

Re: I'm not so sure that options are the answer to why Office is so popular

You missed another key problem with LibreOffice. Track changes. Maybe it's improved, I don't know. But I had to give up on using LibreOffice for any usage involving change tracking. The usage model was bi-directional, I created files and sent to them for them to mark up and send back; they created files that I got, marked up, and sent to them. The changes were not reliably marked, and comments were often not coming through. Those using only Word had no issue. Oddly, docx vs odt didn't seem to make a difference on change tracking. (Sometimes I'd accidentally send them odt, which generated a warning for those using Word, but that was about it.)

I consider Word's change tracking incredibly primitive, but this is a case where it isn't good enough to work with your own product (and I wouldn't consider LibreOffice passing even that low bar on the inserted comments), you have to work with what others around you use.

Re: I think you underestimate it...

$100/year is considered highly competitive for decent automatic backup tools. O365 has more storage than most of the ones I've evaluated, better accessibility, better agent for doing the backups, etc. Oh, and you get access to the office suite as a part of that same cost.

I pay for O365 for the Onedrive storage as a remote backup service. Is it the only copy of my files? No, it's the backup, automatically maintained, and now if a family member deletes a file they didn't mean to, they don't need me to come over and show them the arcane methods to restore that one file. I don't get complaints about their computer being too slow to discover that the backup agent is taking 100% CPU, every other week.

Every remote backup service has similar terms, I just find Microsoft to have the best deal right now.

You like JavaScript! You really like it! Scripting lingo tops dev survey of programming languages

Re: Oh dear! Nothing is perfect

The very reason I find myself willing to work with javascript comes down to two reasons.

First, I recognize it is a purpose built language, not a general purpose language. Just like awk is purpose built to stream process text files. Sure, I can use awk to calculate mathematical problems, but that isn't the design of it. Javascript is similar, in that it is designed to be used for a specific use case.

Second, because I recognized long ago that Javascript is functional first, object oriented a distant third. Even the scoping rules make more sense in that context.

I think if Javascript didn't have those first four letters in its name, no one would care about OO in it or not, except the OO zealots who insist that everything be OO, even if it makes no sense for the problem to be solved.

Exchange is, whether people like to admit it or not, one of the top integrated enterprise calendaring tools available. It supports plugins for various web meeting tools (e.g. BlueJeans, WebEx), and a very effective scheduling tool. It even supports managing conference rooms.

Re: That's nice dear ...

I tried Outlook. It failed the Google Calendar test, unable to display all the calendars shared with me. Thunderbird was the first client on Windows that could work with Exchange, Google, and local calendars. (On macOS, the native calendar worked).

Talking to a few of my peers, they ended up using their mobile phones for such, but given the "we own any android/iOS device that connects to our calendar" trends, that's not very attractive to me.

mini TOSLINK gone?

When I looked at it, the specs seem to imply that the combination headphone/microphone/mini-toslink port is now just a headphone/microphone port.

If you have to simulate a phishing attack on your org, at least try to get something useful from it

Removing the stigma against false positive reporting is important. If you aren't reporting false positives, you aren't reporting real phishing events. Err on the side of reporting. Build that culture of acceptance to presume *any* unanticipated email with links or instructions from the outside is a phish and you'll drop your click rate significantly.

What's the metric?

In any effort like this, one of the things a good manager wants to know is how do we measure this so we know if it is effective? What is the method to measure improvement? Number of clicks? Number of repeat clicks? As the article says, someone will always click. In one phishing training I saw, the security team member clicked on the link and was literally typing in their live username and password, "to be helpful".

I argue that the critical missing metric is time based. How long until that first report? How long until that first click? Can we get people trained to report these things quickly, alerting the trained staff fast enough that they could actually respond and block the malicious URL before the first click? It's ambitious, but it gives you a real measure of your window of vulnerability and your ability to contain the damage.

Ask black hats how common black hats are...

When I've talked to companies, the executive leadership are so terrified of insider threats, so out of proportion to the actual risk, that often they create a bigger security risk by giving the security team, the very team most likely to go black hat, massive access to every piece of intellectual property in the company, even if they don't actually need that access, because security.

Then I talk to the black hats of security, penetration testers, and they talk about insider threats as the number one source of problems.

Then I sit down and look at the company, and see that the top source of risk isn't a malicious actor at all, and often isn't even adversarial, but structural due to their failure to invest in basic IT. Surveys like this aren't very useful except for fear mongering and encouraging further black hat activities by people with security jobs.

Pen testers are not risk assessors

I've had to clean up the mess a pen tester left more than once. They create artificial flags that have nothing to do with the actual valuable data of the corporation, declaring complete success when they get to a resource that is relatively low value (not SOX, not the primary product of the company, not publicly available,...), often engage in dodgy business practices like stepping outside the confines of the test (e.g. engaging in the pen test before they're supposed to start), rarely emulate specific threat actors, often mixing techniques from one threat actor with methods used by other threat actors, completely ignorant of the actual risk profile of the organization, all in an effort to scare people to pay them more money.

In one case, the pen testers required me as a defender to actually not engage in normal defensive actions that were part of my everyday job, like blocking attackers detected through automated reports and systems. Often, pen testers are given these blank check views by requiring the security teams to temporarily disable key defensive systems, at least for the attackers' source IP block.

It's long past time to recognize that a pen test is not a replacement for an actual risk assessment that evaluates all types of risks, adversarial, structural, envrionmental and accidental. Management that I talk to is getting risk fatigue, where they start to see pen testers as chicken little, so the theoretical value of the pen tester, to shock management into paying attention to security, is having the opposite effect, blinding management to a more detailed and strategic view of where the security dollars can be most effectively spent to reduce the overall risk to the company.
