Alert Logic Requirements for Virtual and Physical Appliances
Requirements for Alert Logic virtual appliances
The following table describes the basic system requirements to install a virtual appliance:
| Components | System Requirements |
|---|---|
| CPU | 4 virtual CPUs |
| RAM | 8 GB |
| Disk space | 40 GB minimum |
| Supported virtual environment | VMware only |
| Log collection support | Syslog via agent or agent-less, Windows and flat-file via agent only |
| Encryption | TLS Standard (SSL): 2048bit key encryption, 256bit AES bulk encryption |
Bandwidth volume directly impacts the ability of the appliance to inspect traffic. Therefore, high traffic environments may require a virtual machine with additional processor and memory resources.
If you want to run scans, consider 8 virtual CPUs (cores) and 16 GB of memory.
Physical appliance
The following describes the basic requirements to install a physical appliance:
| Components | System Requirements |
|---|---|
| CPU | Intel Xeon |
| RAM | 4 GB DDR3 |
| Disk space | 500 GB |
| Chassis | 1U rack mounted |
| Power | 250W |
| Log collection support | Both agent-based and agent-less Windows, Syslog, flat file log collection |
| Encryption | TLS Standard (SSL): 2048-bit key encryption, 256-bit AES bulk encryption |
Requirements for Alert Logic Log Manager appliances
Remote collector
The following describes the basic requirements to install a remote collector:
| Components | System Requirements |
|---|---|
| CPU | 2 cores |
| RAM | 2 GB |
| Disk space | 10 GB minimum |
| Supported Operating Systems | Windows and Linux |
| Log collection support | Syslog only via port 1514 |
| Encryption | TLS Standard (SSL): 2048-bit key encryption, 256-bit AES bulk encryption |
| Log collection frequency | Every five minutes (minimum)- logs collected and sent to Alert Logic Cloud |
| Host permissions | LocalSystem account has all the requisite permissions by default |
The following describes the basic requirements to install a physical appliance:
| Components | System Requirements |
|---|---|
| CPU | Intel Xeon |
| RAM | 4 GB DDR3 |
| Disk space | 500 GB |
| Chassis | 1U rack mounted |
| Power | 250W |
| Log collection support | Both agent-based and agent-less Windows, Syslog, flat file log collection |
| Encryption | TLS Standard (SSL): 2048-bit key encryption, 256-bit AES bulk encryption |
Virtual instance without the agent
The following describes basic requirements to install a virtual instance without the agent:
| Components | System Requirements |
|---|---|
| Virtual CPUs | 2 |
| Storage | 20 GB |
| Memory | 2 GB |
| Virtual Network Interface(s) |
Virtual network interface(s) One interface with DHCP or manual IP addressing for management If access to customer assets are restricted from management interface, an additional interface, internal to the customer environment with static access, is required for scanning. VMWare OVF Tool (for more information see VMware OVF Tool) |
Requirements for Alert Logic Web Security Manager Premier appliances
VMware virtual appliance
The following table describes the basic system requirements to install a VMware virtual appliance:
| Components | System Requirements |
|---|---|
| CPU | 2 CPUs 64 bit |
| RAM | 4 GB |
| Disk space | 250 GB |
| Virtual network interface(s) | An interface with an external IP address for management An interface with access to the web servers to be protected |
| Encryption / Decryption for SSL traffic | AES-NI CPU instruction set for encryption/decryption of SSL traffic on VMs and host OS is recommended |
| Clustering | For clustering to work, make sure promiscuous mode, forged transmits, and MAC address changes are allowed on the VMware virtual switch (vSwitch) or the port group in the VMware ESX network configuration |
Physical appliance
The following table describes the basic system requirements to install a physical appliance:
| Components | System Requirements |
|---|---|
| Equipment | 100–250 Mbit |
| CPU | Intel Xeon E3 4 cores |
| RAM | 8 GB |
| Disk space | 500GB |
| Chassis | 1U rack mounted |
| Power | 250W |
| Log collection support | N/A |
| Encryption |
TLS Standard (SSL): 1024–2048bit key encryption, 256bit AES bulk encryption |
Processing Capacity
The following table describes the bandwidth limits for the Managed WAF physical appliances:
| Appliance type | Throughput | Number of virtual hosts | Number of SSL certificates | Number of proxies |
|---|---|---|---|---|
| Tier 1 - R410, R220, R230 | 0-250 Mbps | 1000 | 100 | 200 |
| Tier 2 - R630 | 250-1000 Mbps | 1000 | 100 | 200 |
This is the recommended basic configuration for the Web Security Manager product when deployed on a virtual appliance. Bandwidth volume directly impacts the ability of the appliance to inspect traffic. Therefore, high traffic environments may require a virtual machine with additional processor and memory resources.
If you want to enable scans, the recommended configuration is 8 virtual CPUs and 16 GB of memory.
