Java Implementation of Radius secondary verification based on RSA securID (PAP authentication method) and securidradius
Secondary Verification Based on rsa SecurID. The RSA server itself can be used as a Radius server, RSA can also be used with other software sets, and other servers can be used as a Radius server.
The general process of radius verification is as follows:
The main Code implemented in java i
A common security method used for online banking are to ask the user for three random characters from a passcode. For example, if the passcode is 531278, they may ask for the 2nd, 3rd, and 5th characters; The expected reply would be:317.The text file, Keylog.txt, contains fifty successful login attempts.Given that the three characters is always asked for on order, analyse the file so as to determine the sho
, ready to do some serious damage. That's not a good thing.This, of course, raises another question: Should I use the same key for other servers? As I have just described, this can be dangerous.Finally, it sounds a mess, but there are some simple solutions. You may wish to introduce them individually.(Note: In addition to just logging into the server, there are a lot of places to use the key, but I introduced this scenario to show that you are dealing with the key problems.) )Pay attention to th

such as Symantec.2) night dragon attack against the US Department of Energy: attackers first collected SQL injection vulnerabilities on WEB servers of many energy departments, attacked and controlled these WEB servers. However, this is not what the attacker wants. On these websites, the attacker places a 0-day Trojan attack code for IE and OFFICE applications on some pages that are accessible to internal personnel, because it is difficult to detect internal sites by Trojan, and the scope of the
More than 2/3 of respondents, a survey found, said they are likely to use mobile phone-based verification in the future, and more security token users are anxious about the two-factor authentication technology.
The survey was conducted by PhoneFactor, which sold two-factor phone-based authentication without a token. The survey found that some organizations are considering other two-factor authentication options.
Among the 400 IT professionals surveyed, 93% of respondents who currently deploy tok

choice for many network administrators, but PcAnyWhere also has its shortcomings. Its password file is reversible. In case of intruders getting WebShell, if the Administrator is improperly configured, the attacker can get the connection password, and the consequences can be imagined ......Readers may have said, "Can I restrict remote management of a specific IP address ?" Yes, this is a solution, but it is not perfect, because sometimes the server is in an emergency, but the Administrator is no
IP address has been 61.52.80. *, but recently it has become 221.15.145 .*. In this case, only a fixed IP address can be managed.
Since Version 11.0 of PcAnyWhere, it supports SecurID dual authentication. Using SecurID authentication, you do not need to restrict the IP address at all. The other party cannot connect even if they know the user name and password of PcAnyWhere.
