Is an anti-virus tool for Linux (ex. Sophos) necessary?
Many Linux users claim they have nothing to fear as hackers primarily create viruses for Windows machines, but is that a good enough reason to not install an anti-virus tool?Sophos came out a few years ago making the claim that no machine was safe. They claimed that Linux was susceptible to viruses/attacks and has been attacked in the past. Many people thought they were BSing and asked Sophos to "put up or shut up" with proof of their claims and I'm unsure if they ever came around to providing that proof.What do you guys think? Is it worth the download?

Anyone seen this? (IE with green border and "Encrypting" keyboard symbol bottom right). Not sure if malware or some keystroke masking software.

Secured and unsecured home environments
Hi all,I am leaning toward buying or building a windows machine dedicated strictly to processing sensitive personal transactions. Does anyone else do this?How I would protect:-Dedicated network interface and network -wired connection -Security suite (Bit Defender or Norton, leaning toward Norton) -dedicated printer/scanner -strict firewall rules to lock down egress in addition to the default implicit deny. -Geo IP range blocking -Dedicated e-mail address used only for services to be used on the secured networkAnything obvious I am missing?If you do this, what sort of activity do you classify as sensitive or to be processed on the secured network/device?I am thinking anything that involves obvious PII/HIPPA type Information.Banking, brokerage, health insurance/medical issues. I would consider possibly shopping but part of me is a little hesitant to include it there. There must be a point at which there is a cut off otherwise one could argue everything is important including social media, YouTube searching and general googling. At that point there would be no difference between the unsecured and secured networks since I would generally set them up in almost the same way anyway, aside from strict egress lockdown.

JavaScript that detect hosts in my local net
I am fallen in a web page (https://www.cleancss.com/router-default/ZyXEL/P-660H-D1) that "scan" (or try to) my local network looking for devices. Just for curiosity, i take a look to the source code and I found a javanoscript that seems to be able to scan my localnet:https://pastebin.com/7bvHaRwnThat's safe ? Is possibile to write down a JS that scan my localnet and send results to outside server ?A bit afraid.

Provider storing passwords unencrypted/hashed
I was wondering, why my provider would verify my identity by asking for the 3 first signs of my password. So i asked them by email and they told me it would'nt be necessary. Only the first 3 signs are known to them. Is this plausible, or is my password stored in an unencrypted database which could potentially be hacked? How would i go on on convincing them to change this?

Overall Security Strategy
I'm looking to begin a new security strategy for my colo'd server. I'm very interested in cyber security overall and would like to explore some of the different areas within. I enjoy hands on experience and learn best from it as well.I have a colo'd server which publicly hosts stuff and also has my "lab" on it. I'm looking to develop a security plan to better protect the VMs and overall network. VMs range from linux variants to windows ~20-30VMs total.I want to be able to emulate an enterprise as close as possible to learn more about the different aspects. Of course this starts with AD and tieing in SSO for apps and stuff. I would like to know what type of software I should look into and what log aggregation stuff I should use (I've worked with Splunk a little). I also like the idea of Security Onion which uses ELK so that's an option too since I'm sure it'd easily ship the logs to a centralized server. That covers network IDS and packet logging etc. On the hosts for linux and windows, what should I use for HIDS or other malware scanners that can communicate to a "centralized" server. I saw something about OSSIM but would like community input.Aside from network and host based stuff talked about above, is there anything else I should look into? If you have a diagram that talks about the different security areas of a network (such as network and host based (and more) that I can use as a "checklist" that'd be great.

Slow loris noscript not working properly
Hello everybody!So recently I learned about the Slow Loris attack and thought about testing it against my rpi server. So now matter how high I set the number of connections to be, the server still worked, it only worked slower, but for short intervals of time. Here is the code I used! Does anyone have an idea why it doesn't work properly?
