![]() You can only use Digital Encryption if you use a Digital medium. You can use both types of encryption in an Analog medium. We basically have two types of radio transmission mediums: 1. I will outline a few possibilities here, but first, a little background. The basic rule of thumb is: the more you spend, the better your encryption. There are different forms and security levels of encryption. The only way to achieve COMSEC is through encryption. If at any time you feel your radio communications are vulnerable you have completely lost OPSEC. Once you have achieved COMSEC you can feel free that any use of your radio communications gear will not effect OPSEC. Whether we are talking about security of a SWAT or SRT team, or the personal safety to Search & Rescue Team members, OPSEC is paramount.ĬOMSEC consists of securing your radios well enough that your internal communications can not be monitored. OPSEC means the security of the complete operation. Though quite different in overall meaning, both terms go hand in hand and you can not achieve one without the other. Two key elements in Tactical Operations are OPSEC (operational security) and COMSEC (communications security).
