Secure, HttpOnly and SameSite Cookies: What the Flags Mean

Cookie attributes influence when cookies are sent, whether browser scripts can read them, and how they behave across sites. They are small settings with important security and privacy consequences.

Short answer: Cookie attributes influence when cookies are sent, whether browser scripts can read them, and how they behave across sites. They are small settings with important security and privacy consequences.

Secure restricts transport

A cookie marked Secure is intended to be sent over HTTPS rather than ordinary HTTP. Sensitive session cookies should normally not travel over an unencrypted connection.

HttpOnly limits script access

HttpOnly tells the browser not to expose the cookie through normal JavaScript document-cookie access. It can reduce the impact of some script-injection scenarios involving session cookies.

SameSite affects cross-site sending

SameSite controls when a cookie is included in cross-site requests. Lax, Strict and None represent different trade-offs between functionality and cross-site exposure.

Not every cookie is a login session. Analytics, preference and consent cookies have different sensitivity. Observe shows visible cookie attributes so the purpose and configuration can be reviewed together.

Field experience from the archive

Historical source · JufCorp: Securing your server environment - Part III - Operating systems

Now, this is a bit tricky but it may very well be worth the trouble There are fairly easy ways to implement executiion deny policies on servers ie only allowuing scripts and executables to be run from specific locations. If you know all paths where scripts and executables will be frun from , why not turn that on ? That way you will restrict any weird executions from %temp% etc

Practical review checklist

Frequently asked questions

Should every cookie be HttpOnly?

No. Some cookies intentionally need browser-script access, but sensitive session cookies often should not.

Why does SameSite=None require care?

It allows cross-site use and normally requires Secure, so the reason for cross-site behavior should be understood.

Check the evidence with Scantide Observe

Browser-visible website security and privacy evidence. Scantide is designed to show observable evidence and readable context rather than turn every observation into a vulnerability claim.
