This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started). Mostly now the topics are about IoT and SD-WAN.

Visitor identity is crucial to the effective security of an estate or complex. Manual visitor record books are ineffective means of management as information is largely inaccurate and mostly illegible. With the implementation and roll out of the Protection of Information (POPI) Act, paper based access control registers are no longer compliant and will soon become obsolete. OnGuard has developed a modern solution for its replacement called Identiscan, a hand-held mobile data terminal effective in scanning both motor vehicle and driver licences. The Identiscan electronic visitor management system (EVMS) ensures all data is encrypted and stored offsite on a secure server. The guard managing the IdentiScan scanner must first correctly identify himself using his personal PIN before he can collect data, ensuring accountability for management of the scanner as well as the allocation of the access record to the specific guard. No longer can a staff member say “It wasn’t me who let the visitor in”.
Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use.

When building a DDoS mitigation service it’s incredibly tempting to think that the solution is scrubbing centers or scrubbing servers. I, too, thought that was a good idea in the beginning, but experience has shown that there are serious pitfalls to this approach.
