With Linux and ZFS, QuTS hero supports advanced data reduction technologies for further driving down costs and increasing reliablility of SSD (all-flash) storage. QuTS hero is the operating system for high-end and enterprise QNAP NAS models. WIth Linux and ext4, QTS enables reliable storage for everyone with versatile value-added features and apps, such as snapshots, Plex media servers, and easy access of your personal cloud. Key point I'm trying to make here is the email server side is what should really be beefed up if it isn't.QTS is the operating system for entry- and mid-level QNAP NAS. Sorry for sounding like an advertisement, but this is a true testimony. We still get occasional spoofed emails, but I'm not as worried about that since our users are fully aware of what to look out for and to verbally confirm with anyone before wiring money. Since enabling ATP we have not had a single incident with emails. Email is our biggest risk and they have nearly taken all the risk out since all attachments and links are scanned on the server side before it reaches the end user. I have to say Microsoft is doing a great job of preventing incidents for us. We are small company using Office 365 and after a few incidents we had, we opted for the advanced threat protection. #Hopw to update clamxav zipThese files can be scanned, enclosed files like ZIP can be opened and scanned.Įdit I agree with : squid - and other comparable tools, are things of the past.Įdit: On a more serious note though, the most effective solution I have found for preventing security issues has been on our email server side. Virus scanning etc is still useful today for mail protection : all mail comes in on port 25 - TLS encrypted of course, but it winds up in a mail box, using clear text: just a folder with mail files. #Hopw to update clamxav how to"Internet users", like "car users", "TV users", etc should follow some sort of 'eduction' about how to use it up front. Today, network protection can not be centralized on one place (firewall) any more. No one sniffs through other person's chat's and mails any more. freshclam is the automatic database update tool for Clam AntiVirus. With your router handling 99,99 %% TLS encoded traffic ? I do NOT want to have the latest package release, I want to have the stable said in How to update ClamAV: Most servers, available on the Internet, that use ClamAV, has this line it it'log. You shouldn't abandon ClamAV for this message. It took me months before I got it fine tuned to a point of very few false positives. In my experience, the majority of my false positives came from suricata. Do them one at a time and don't dive into both right away, because if you start getting a lot of false positives, you will have a difficult time tracking down which tool is blocking the site. If you haven't already, I would say try starting with pfblocker first, then later with suricata. There is a learning curve especially with suricata, but the devs of both suricata and pfblocker usually answer questions right on these forums very quickly. It will also require some fine tuning to avoid false positives and legitimate sites being blocked. Suricata (intrusion detection/prevention) is also another package I use for network security. Pfblocker is very actively maintained and there is tons of information, guides, and recommended lists for pfblocker. I believe squidgaurd can also be used for URL filtering, but what I last recall is that the squid package not getting nearly as much attention or upkeep, if at all. Take it easy with adding lists to start off. In other words, you may have to whitelist certain sites that are being falsely flagged as bad. It may take some fine tuning to get your blacklists right. It help prevent access to malicious sites by using maintained blacklists. I'm finding a solution like pfblocker-NG devel to be a better option for network security. You can see the hit rates are extremely low. Below is an old image from when I last used it. Take a look at your squid user access report. Is the primary purpose for squid to act as AV scanning on the firewall?ĭon't take my word for it, check to see if squid is really doing much in your own environment. So, after abandoning squid and ClamAV, what was your alternative?ive?
