So I have a 5505 Unlimited-User and based on the first document I'd need 512MB RAM. &nbsp;Show Version says:<br />
<br />
Hardware: &nbsp; ASA5505, 256 MB RAM, CPU Geode 500 MHz<br />
<br />
Guess that answers my question.<br />
<br />
Thanks

<div class="content wysiwyg-content">
I have an ASA 5505 running an old OS:<br />
<br />
ASA 8.2(5)<br />
ASDM 6.2(5)53<br />
<br />
I have downloaded:<br />
<br />
ASA 9.24<br />
ASDM 7.82<br />
<br />
Which I believe are the newest support OS for the ASA 5505. &nbsp;Is there an upgrade path or can I just upload the bin files and assign them to be used and reboot?<br />

Thanks in Advance

Updating Cisco OS

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

Operating Systems

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
